Diesel engines' benefits

Not just the cleaner fuels that can be used in Diesel engines, there are other benefits.

Its fuel consumption in volume is lower in comparison to gasoline, LPG or ethanol used in the United States, Sweden and Brazil, either using regular petroleum-based Diesel fuel or its vegetable replacements, such as biodiesel or vegetable oils.

Diesel engines are usually more reinforced, turning them the best options to heavy duties. In addition, their torque range at low flywheel speeds provide a better performance in hilly terrain.

Other important consideration is the safety due to its lower electromagnetic radiations emmited, even in these newer common-rail ones, because there is no electrical ignition with those high-voltage coils and all those stuff. By the way, if some health services facilities require us to not use cellphones because the electromagnetic radiation can interfere in all those electric devices, makes more sense to use a diesel engine in an ambulance, for example.

LPG x BioDiesel

LPG was the obvious choice for taxi drivers until some years ago, except for Coupon Taxis and Mega Taxis usually powered by Diesel engines usual to found in nearly any AUV or passenger van. However, it's a gaseous fuel, then harder to handle than a liquid fuel. Also, it's a petroleum-based fuel, not renewable. There is another gaseous fuel highly used worldwide, the methane-based Natural Gas, that can be sourced from landfills and sewage treatment stations. Usually, higher pressure systems are more used with it, so while an LPG system is usually in the 15-bar range a CNG is around 200 to 250-bar. Some low pressure Natural Gas had been used in buses to run on biomethane from pork farms sewage in China, but this is not suitable to smaller vehicles like a Toyota Vios.

For commercial operators, Diesel engines had been proven as unbeatable, due to its improved fuel efficiency and usually more reinforced hardware. The absence of an electric ignition system is also good to heavy duties, such as mining sites, marine applications, industrial power generation and military vehicles. Also, there is the safety factor: Diesel fuel is less volatile, reducing the risk of explosions in comparison with gasoline, alcohol and LPG. Biodiesel has two more advantages: it's renewable and not require foreign materials to be made of. Then, finantial resources remain in the homeland, allowing the generation of jobs for local people.

Biodiesel or straight vegetable oils?/Biodiesel o tuwid halaman ng langis?

Biodiesel is a good fuel for urban applications, since glycerine, its main byproduct, can found some industrial applications avoiding it to be just one more waste to handle with. However, in the countryside, straight vegetable oil is a good option since it requires less infrastructure to be used as fuel, it can be already used pure, not requiring any expensive (and ocasionally environmentally-critical) chemical process. Removing the glycerin from the oil by the trans-estherification process (replacing it by ethanol or methanol) is also good to avoid strange smells from the exhaust smoke due to its burning, but in small villages it wouldn't be so problematic as in a bigger city because of the lacking infrastructure to reprocess the glycerin that could be disposed in a wrong way and then contributing to pollute rivers, the sea and underground water reserves in a smaller village, that also would have a less heavy traffic.


________________________________________________________________________




Biodiesel ay isang magandang pampagalit para sa mga lunsod o bayan ng mga aplikasyon, dahil gliserin, ang mga pangunahing kakambal na produkto, maaari natagpuan ng ilang pang-industriya mga aplikasyon ng pag-iwas sa mga ito upang maging isa lamang sa karagdagang basura sa hawakan sa. Gayunman, sa kanayunan, tuwid halaman ng langis ay isang magandang opsyon na ito dahil ito ay nangangailangan ng mas mababa infrastruktura na gagamitin bilang pampagalit, maaari na ito ay ginagamit purong, hindi nangangailangan ng anumang mga mahal (at paminsan-minsan ang kapaligiran-kritikal) na kemikal na proseso. Tinatanggal ang gliserin mula sa langis sa pamamagitan ng mga trans-estherification proseso (palitan ito sa pamamagitan ng ethanol o methanol) ay din mabuti upang maiwasan ang mga kakaibang pang-amoy mula sa tambutso ng usok dahil sa kanyang nasusunog, pero sa mga maliliit na nayon hindi ito ay magiging gayon katiyakan gaya ng sa isang mas malaki na lungsod dahil sa kulang sa infrastruktura na reproseso ang gliserin na dapat na itapon sa isang maling paraan at pagkatapos ay nag-aambag sa pagdumi ilog, sa dagat at sa ilalim ng lupa tubig Taglay sa isang mas maliit na nayon, na rin ay may isang mas mabigat na trapiko.

would you fit any pre-heat setup into that c240 that you intend to put into a honda legend? btw which generation and body style would you consider to retrofit with the diesel?

Actually the glow plugs already provide an easy cold start capability pero an air intake heater could already be added. For the biodiesel tank and fuel lines it would not be required, and it can already run pretty well with waste palm oil or coconut oil. A filtration system, by the other side, is almost mandatory to ensure the reliability while using waste frying oil. That centrifuge setup used in some Russian trucks seems to be a good option.

About body style and generation, I prefer the 2nd generation coupé due to its sporty look pero maybe will get a sedan because what I want is not exactly a sports car. Would be cool to show how a luxury car can be, by the other side, eco-friendly.

Feel free to question

What's one thing you own that you should probably throw away, but never will?

An old Isuzu C-240 engine taken out of a wrecked jeep. I still wanna put it into a Honda Legend and run it on biodiesel. I can even purchase a newer engine to this project but I already like this one.

Ask me anything

Why biodiesel?/ Bakit biodiesel?

Biodiesel is the most environmentally-friendly automotive and industrial fuel ever, since it can either be made from renewable agricultural feedstocks, organic waste or even sewage, avoiding the underground water to be contaminated and generating less dependance on fossil fuels with a higher carbon dioxide emissions. Even homebrew can be done with waste frying oil.

__________________________________________________________________________


Biodiesel ay ang pinaka kapaligiran-walang alitan na automotiw at pang-industriya pampagalit kailanman, dahil ito ay maaaring alinman ay ginawa mula sa renewable agrikultura feedstocks, organic na basura o kahit dumi sa imbumal, iwas sa ilalim ng lupa ng tubig na kontaminado at pagbuo ng mas mababa dependance sa Fossil pampagalit sa mas mataas na emissions ng carbon dioxide . Kahit homebrew maaaring gawin sa basura magprito langis.
