There are plenty of advantages to diesel engines: High fuel efficiency, low CO2 emissions, and in modern turbocharged applications, plenty of easy-to-access torque and power. However, they aren't ...

Combustion optimisation in direct injection (DI) diesel engines seeks to enhance fuel–air mixing, improve thermal efficiency and mitigate pollutant formation within increasingly stringent ...

Automotive engineers are very good at incremental improvements to existing technologies, and that skill will be much tested in meeting increasingly stiff fuel-economy rules between now and 2025. For ...

Diesel engines lack the spark of gas engines, both literally and figuratively. They don't need a spark plug since they ignite the fuel using only compression, but also lack the 'je ne sais quoi' that ...

The once-almighty Mitsubishi Motors may have relegated themselves to building cheap small cars and Nissan-derived crossovers, but it was an indomitable powerhouse of innovation back in the day.

Direct injection, as the name suggests, refers to a type of fuel system which introduces fuel directly into an engine's combustion chambers. This differentiates it from conventional injection systems ...

It's an amazing time when there's new technology in the industry as it forces a new rivalry in speed parts, and direct-injection is firmly in the high-performance arena whether anyone likes it or not.

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 ...

How does direct fuel injection work? Instead of having injectors in a throttle body, or in the intake manifold, a direct injection system makes use of an injector that fires into the combustion ...
