Castor oil is reported to be quite thick in comparison with other oils, but has some recognized lube properties in 2-stroke spark ignited engines. But using the pure oil as fuel is supposed to not damage the engine. It's just a trouble when there are rubber parts on the fuel lines.

Diesel motorcycles: yes we can!
Usually, motorcycles are more associated with lighter and higher-RPM gasoline-powered engines, but it's not every time the only option. And I'm not talking about ethanol commonly seen in Brazil (Honda even offers some flexfuel motorcycles, including the very first one in the world, and its avant-premiere took place in Brazil where ethanol has an enormous market share in the energy market) or CNG/LPG widely used in China (currently in some cities such as Shanghai new motorcycles can be registered only if powered either by CNG or LPG). Hell yeah, I'm talking about diesel bikes.
Better known for their use by the U.S. Marine Corps, diesel motorcycles were also quite common in India, where even the traditional Royal Enfield offered its own diesel-powered version, actually equipped with a modified version of the 350cc gasoline-powered 18hp engine (just 6hp in diesel version) until Bharat Stage-II emission laws started to get enforced. But it didn't phase them out at all, since there were some Royal Enfield owners swapping the 400cc single cylinder 8hp engines available for some autorickshaws into their bikes. It's also a reasonably popular mod among Royal Enfield enthusiasts in Europe, most notably in Germany, and some even run on biodiesel.
So, even with all those misconceptions about diesels and bikes, they can match really well.
What about a Honda XL with a 400cc diesel? A great choice for somebody who wants a reliable and extremely fuel-efficient off-road vehicle to get some fun in trails.
Oh, seems like I forgot the Harleys and their distinctive shape with those low specific power V-Twins. No doubt they would be a perfect match for those Chinese V-Twin 22hp industrial diesels.
But one thing must never be forgotten: when we ride bikes, protective equipments such as helmets are a must.

How can I make my NIssan XTrail's X-Tronic CVT automatic transmission operate properly behind a diesel engine? I'm considering to swap a surplus TD27 into my vehicle but since the CVT even increases its fuel-efficiency I would prefer to retain it.
You would need an auxiliary electronic module to run the transmission electronic controls as a stand-alone unit. You would need to emulate the signals from the original engine control module, such as the throttle-body position (absent in a diesel engine), injector tips and the spark ignition system. An output from the alternator would work for the RPM detection. There are already some plug-and-play devices to perform this control for American heavy-duty automatic transmissions but for a Japanese vehicle with a transverse engine I've never seen it so easily available.
I agree with you about the CVT to increase the fuel-efficiency, and it also would be better to retain this transmission because of the improved comfort over a manual one.

Bakit ka kaya gumon sa diesel engine? Huwag galit ka gasolina pinapatakbo engine? Ano ang inyong opinyon tungkol sa natural gas para sa mga sasakyan?
Mas gusto ko ng diesel engine dahil sila ay may ng mas mahusay na pagganap para sa mabigat na tungkulin at ang compression ignisyon ay kaakit-akit. Actually, hindi ko napopoot gassers, pero napopoot ko ang lahat ng mga sponsors digmaan na gumagamit ng pera mula sa nagbebenta ng gasolina para pananalapi insults laban sa mga indibidwal na kalayaan sa buong mundo. Tungkol sa natural gas, hindi ako isang tagahanga ng mga ito pero tila na maging mabuti na gamitin sa pang-industriya powerplants.
I prefer diesel engines because they have a better performance for heavy duties and the compression ignition is fascinating. Actually, I don't hate gassers, but I hate all those war sponsors that use money from gasoline sells to finance insults against individual freedom all over the world. About natural gas, I'm not an enthusiast of it but seems to be good to use in industrial powerplants.
Huwag kang magtrabaho kasama ng iba pang mga tatak diesel engine o lamang Isuzu?
Lagi ko na na mas nakatutok para Isuzu pero din ay may ilang karanasan sa galaw at agrikulturang engine mula ibang gumagawa katulad ng Komatsu, Kubota at Perkins.
I've always been more dedicated to Isuzu but also have some experience with stationary and agricultural engines from other manufacturers such as Komatsu, Kubota and Perkins.
I'm from Davao City, recently bought a '96 surplus Ford E-350 ambulance with the 351 V8 but unhappy with its fuel consumption, considering a diesel swap. What would be your advice? I don't care about the automatic gearbox, no problem to swap it for manual
A very usual option to repower these full-size American vans have been surplus drivelines from the Nissan Patrol/Safari but since the vans usually remain RWD only the transfer case and front axle of the Nissan are not used. The transfer case, however, could be good to retain and use as a kind of auxiliary transmission due to its low range favorable to uphill drive. But instead of the LD28, RD28 or TD42 inline-six engines from Nissan I honestly believe you would be OK with the Isuzu 4.3L 4HF1 out of an NPR or a 4.6L 4HFG1 from the NQR, both have a good torque and wouldn't be so tight to fit into the engine bay. Also, since Isuzu trucks use cable-shifted transmissions it would also be a good option because you would have more freedom to put the shifter in a place where it would be easily accessible and more comfortable to operate.
Gusto sa isang Chevy Tahoe GMT800 maging OK sa mga engine at ang awtomatik na transmisyon gikan sa sa isang bagbag Isuzu Alterra?
Oo, ang Isuzu 4JJ1-TC ay dakilang pagpipilian para lumipat ng GMT800 pero kinakailangan mong mag malaman itoy ilagay sa alanganin ang hila kapasidad. Ito ay tulad ng hilahin ang Vortec 4.3L V6 pero gumastos mababa sa diesel kay sa V6 ay gawin ang sa gasolina.
Sure, the Isuzu 4JJ1-TC is a great option to move a GMT800, but it would compromise the towing capacity. It would pull like the Vortec 4.3L V6 but spends less on diesel than the V6 would do with gasoline.

What would be a good diesel engine option for a Volkswagen Beetle? If possible I would like to retain it air cooled but Lord willing I can go for a water cooled engine. I'm in San Fernando, Pampanga.
For air cooling you must check some industrial/stationary engines. There is a lot of Chinese ones being imported. Anyway, if you just want a commuter, you can even get a V-Twin 22HP air cooled diesel. As far as water cooling goes, you could get a wider power range to choose, but then you would need to figure out the best way to get a radiator and it would increase both the engine swap and the maintenance cost. I actually have considered to buy a Volkswagen Brasilia to swap a diesel into, but the C240 I currently have is too heavy and would not fit easily. But if you would want something more car-like than an industrial engine take a look at some European imports such as Audi cars with their TDi engines, and even some Opels that were offered with Isuzu engines in its diesel versions.
What about sewage treatment residues to biodiesel production?
At least the methane can be turned into fuel oil after the Fischer-Tropsch process, commercially done nowadays by SASOL in Mozambique with fossil natural gas. There are also some fatty residues on the sewage, mostly from bacteria cellular walls, that could also be used in biodiesel production.

2-cycle diesels: a good way to save fuel (and raw materials)
Once they dominated the American roads under the cowls of virtually every truck manufacturer established in the United States, but now they're basically only avaliable for large ships or electric powerplants where an increased power-to-weight ratio would be nearly mandatory. But 2-cycle diesels are still a great layout for on-road purposes.
The most remembered 2-cycle diesels are the early Detroit Diesel engines, made by General Motors' former GM Diesel division since 1938 and currently only avaliable in a version made by the German company MTU mainly for military purposes. Those were known for their distinctive sound, with a belt-driven Roots-type supercharger, usually reported to be essential to provide the air amount necessary to these engines. However, in 1999 Yamaha shown a different 2-cycle diesel layout that didn't require any supercharger - unfortunately it was never released commercially.
Differently to the spark-ignited 2-cycle engines, diesel ones can have exhaust valves. The old Detroit Diesels had exhaust valves, except for the rare Series 51, never reported to be used for automotive purposes. Some large ships don't have exhaust valves, because their engines are already too big, heavy and expensive, and a valve train would be only one more feature to increase the cost, weight and demand mantainance procedures.
2-cycle diesels had also been used for aircrafts before World War II, usually with piston-ported layouts. Currently, with all the concernments about AvGas avaliability and cost, 2-cycle diesels had been again in evidence for the aeronautic industry. As diesel engines are usually heavier than their spark-ignited counterparts, the 2-cycle layout has been preferred on the development of aeronautic diesel engines to face its competitors, usually 4-cycle. Since they can use nearly every heavy fuel, from regular diesel to jet fuels, going through biodiesel and synthetic fuels, it's another advantage. One of the companies involved with 2-cycle diesels reintroduction not just to the aviation, but also to the industrial engines segment, is American DeltaHawk engines. The valveless design chosen for the engines allows a greater weight reduction without sacrifice the reliability. Actually, with less moving parts to increase mantainance costs it can even be considered an improvement for the reliability.
Another advantage from 2-cycle diesels is the smaller amount of raw materials required to make one, then reducing its cost and the environmental impact from production processes. As we can see, they're a great option to meet the needs of the truck and bus (and jeepney) market segments.

Kapag sila ay dominado ng mga Amerikano mga kalsada sa ilalim ng cowls ng halos lahat ng tagagawa ng trak na itinatag sa Estados Unidos, ngunit ngayon sila talaga magagamit lamang para sa mga malalaking ships o electric powerplants kung saan ang isang nadagdagan ang ratio ng kapangyarihan-sa-timbang ay halos sapilitan. Pero 2-cycle diesels mga pa rin ng isang mahusay na layout para sa on-road na layunin.
Ang pinaka remembered 2-cycle diesels ay ang unang bahagi ng Detroit Diesel engine, na ginawa ng dating division General Motors 'GM Diesel mula noong 1938 at kasalukuyang magagamit lamang sa isang bersyon na ginawa ng mga Aleman MTU kumpanya higit sa lahat para sa militar na layunin. Sa mga ay kilala para sa kanilang natatanging mga tunog, na may isang belt-driven Roots-uri panaksak na lansungan, karaniwang iniulat ay mga pangunahing bagay upang magbigay ng mga hangin na halaga na kinakailangan upang ang mga ito engine. Gayunman, sa 1999 Yamaha ipinapakita ng ibang 2-cycle diesel layout na hindi nangangailangan ng anumang mga panaksak na lansungan - sa kasamaang palad ay hindi kailanman ito ay inilabas sa komersyo.
Naiiba na ang spark ignited-2-cycle engine, diesel iyan ay maaaring magkaroon ng tambutso valves. Ang lumang Detroit Diesels had tambutso valves, maliban para sa mga bihirang Series 51, hindi na iniulat na gagamitin para sa layunin ng automotive. Ilang malalaking barko ay wala tambutso valves, dahil ang kanilang engine ay na masyadong malaki, mabigat at mahal, at ang isang balbula tren ay isa lamang sa karagdagang tampok upang madagdagan ang halaga, timbang at demand mantainance pamamaraan.
2-cycle diesels ay nagkaroon din ay ginagamit para sa sasakyang panghimpapawid bago ang World War II, ay karaniwang may piston-port mo layout. Sa kasalukuyan, kasama ang lahat ng tungkol sa concernments AvGas avaliability at gastos, 2-cycle diesels ay muli sa katibayan para sa aeronautic industriya. Bilang diesel engine ay karaniwang mas mabigat kaysa sa kanilang spark-ignited counterparts, ang 2-cycle layout ay ginustong sa pagpapaunlad ng aeronautic diesel engine sa mukha nito kakumpitensiya, karaniwan 4-cycle. Dahil maaari nilang gamitin ang halos lahat ng mabigat na fuel, mula sa regular na diesel fuels sa jet, pagpunta sa pamamagitan ng biodiesel at gawa ng tao fuels, ito ay isa pang bentahe. Isa sa mga kompanya na kasangkot sa 2-cycle diesels reintroduction hindi lamang sa mga abyasyon, kundi naman sa pang-industriya segment engine, ay American DeltaHawk engine. Ang valveless disenyo pinili para sa mga engine ay nagpapahintulot sa isang mas higit na pagbawas ng timbang nang walang sakripisyo ang pagiging maaasahan.Actually, na may mas mababa paglipat ng mga bahagi upang madagdagan ang gastos mantainance maaari ito kahit na itinuturing na isang pagpapabuti para sa pagiging maaasahan.
Isa pang bentahe mula sa 2-cycle diesels ay ang mga mas maliit na halaga ng hilaw na materyales na kinakailangan upang gumawa ng isa, pagkatapos ay pagbabawas ng kanyang gastos at ang mga epekto sa kapaligiran mula sa proseso ng produksyon. Bilang maaari naming makita, na ang mga ito ng isang mahusay na opsyon upang matugunan ang mga pangangailangan ng mga truck at bus (at jeep) segment ng merkado.
