If you think direct-injection diesel engines made their debut in the 1980's, think again. The first diesel without extra ...

Westport Innovations Inc. on Tuesday announced a second-generation high-pressure direct-injection natural gas system usable on original equipment manufacturers’ diesels. It replaces the dual-fuel ...

Direct injection. Just about every car has it now, and those that don’t probably will in the next few years. It can add power, reduce emissions, and is a big part of why just about everybody is ...

The fuel injection pump is the heart of the diesel engine. Precisely delivered fuel maintains a rhythm or timing that keeps the engine running smooth. Simultaneously, the pump also controls the amount ...

There are numerous differences between diesel and gas engines, including the number of fuel filters each uses. Here's why ...

The basic difference between direct injection (DI) and the port-fuel injection (PFI) systems we've become familiar with since the mid-1980s is that PFI sprays fuel into the intake manifold (behind ...

The present study focuses on evaluating split-injection strategies in an ammonia–diesel dual-fuel (ADDF) engine at 1800 rpm under medium load conditions, a load range of particular interest in ...

Due to the design challenges and low performance of engines in green fuels, the researchers started to investigate fuel blends. The inlet parameters also will influence the performance and, emission ...

The carbureted car and truck era phased out by the early '90s. Carbs are still in use today on a few motorcycles, lawn mowers, and other power equipment, but electronic fuel injection (EFI) is ...

However, not all innovations are equal, and nor do they follow a constant upward trend. Instead, their evolution takes the form of an S-shaped curve that reflects their typical lifecycle from early ...
