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.

LPG ay ang malinaw na pagpipilian para sa mga taxi driverhanggang sa ilang mga taon na nakalipas, maliban para sa Kupontaxi at Mega taxi karaniwang pinapatakbo ng Diesel engine ng dati na matatagpuan sa halos anumang AUV o van na pasahero.Gayunman, ito ay isang puno ng gas fuel, at pagkatapos ay mas mahirap na hawakan kaysa sa isang likido fuel. Gayundin, ito ay isang produktong petrolyo-based gasolina, hindi renewable. Mayisa pang puno ng gas gasolina mataas na ginagamit sa buong mundo, ang mitein-based Natural Gas, na maaaring sourced mula sa landfills at sewage treatment istasyon. Karaniwan, ang mas mataas na presyon ng mga sistema ay mas ginagamit sa mga ito,kaya habang ang isang LPG system ay karaniwang sa 15-barhanay CNG isang ay sa paligid ng 200-250-bar. Ang ilang mgamababang presyon ng Natural Gas ay ginagamit sa mga bus na tumakbo sa biomethane mula sa mga sakahan ng baboy sewagesa Tsina, ngunit ito ay hindi nababagay sa mga mas maliit nasasakyan tulad ng isang Toyota Vios.

Para sa komersyal na mga operator, Diesel engine aynapatunayan bilang unbeatable, dahil sa kanyang pinabuting fuelna kahusayan at karaniwang mas reinforced hardware. Ang kawalan ng isang electric ignition system ay din mabuti sa mabigat na tungkulin, tulad ng mga site pagmimina, marine aplikasyon,industriya kapangyarihan henerasyon at militar sasakyan.Gayundin, diyan ay ang kaligtasan kadahilanan: Diesel fuel ay masmadaling matuyo, pagbabawas ng panganib ng pagsabog sapaghahambing sa gasolina, alak at LPG. Biodiesel ay maydalawang karagdagang mga pakinabang: ito ay renewable athindi nangangailangan ng dayuhang materyales na ginawa ng.Pagkatapos, finantial resources manatili sa sariling bayan, na nagpapahintulot sa henerasyon ng mga trabaho para sa lokal namga tao.
