Hydrotreated vegetable oil (HVO) is a biofuel made by the hydrocracking or hydrogenation of vegetable oil. Hydrocracking breaks big molecules into smaller ones using hydrogen while hydrogenation adds hydrogen to molecules. These methods can be used to create substitutes for gasoline, diesel, propane, kerosene and other chemical feedstock.

2025年2月7日 · Port fuel injection can offer better vaporization under certain conditions. But port fuel droplets can drop out of suspension when they hit the intake valve before entering the combustion chamber. Direct fuel injection is better at cooling the combustion chamber and controlling fuel trims under certain conditions.

2025年3月10日 · But have you ever halted to think about which gas stations have the finest gas? Many gas stations get their fuel from the identical source, meaning the formula doesn’t change substantially. Top Tier stations, though, such as Shell, Mobil, Chevron, Costco, and Sinclair, use additives in their unique mix.

2023年9月12日 · Spark plugs and fuel injectors are two distinct technologies for igniting the air/fuel mixture. Fuel injectors are more technologically advanced and used in modern diesel engines. Meanwhile, Spark plugs are mostly used in gasoline engines and are suitable for both old and new types of engines.

5 天之前 · Reducing CO2 emissions in general aviation is a critical challenge, where battery electric and fuel cell technologies face limitations in energy density, cost, and robustness. As a result, hydrogen (H2) dual-fuel combustion is a promising alternative, but its practical implementation is constrained by abnormal combustion phenomena such as knocking and pre-ignition, which limit the achievable ...
