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, 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 ...

The BMW 3 Series has captured the hearts and minds of automotive enthusiasts and journalists alike, and the attraction is due in no small part to the excellent engines housed beneath any 3 Series hood ...

What it does: The high-pressure system injects fuel directly into each cylinder of the engine to increase power and torque without sacrificing performance or increasing emissions. An advanced engine ...

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 ...

SAE Transactions, Vol. 96, Section 4: RECIPROCATING ENGINES–SPARK IGNITION AND DIESEL (1987), pp. 614-623 (10 pages) A single-cylinder, variable–compression ratio, direct–injection diesel engine was ...

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 ...

The formation of soot during the first phase and the oxidation of soot during the later phase of the combustion in a direct-injection diesel engine have been investigated in detail by an extinction ...

Diesel engines operate at higher compression ratios than gasoline engines, and fuel is injected under much higher pressure. An injection pump, usually driven by a belt or chain linked to the ...

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 ...
