An advantage of indirect injection gasoline engines versus direct injection gasoline engines is that deposits on intake valves from the crankcase ventilation system are washed by the fuel. [2] Indirect injection engines also tend to produce lower amounts of particulate matter compared to direct injection engines as the fuel and air are more ...
An indirect diesel injection system (IDI) engine delivers fuel into a small chamber called a swirl chamber, precombustion chamber, pre chamber or ante-chamber, which is connected to the cylinder by a narrow air passage. Generally the goal of the pre chamber is to create increased turbulence for better air / fuel mixing.
The only thing all fuel injection systems have in common is the absence of carburetion. There are two main functional principles of mixture formation systems for internal combustion engines: internal and external. A fuel injection system that uses external mixture formation is called a manifold injection system.
These engines use an injection pump that is entirely mechanical, as was the standard for diesels of the day. The fuel system also utilizes indirect injection which made it quieter than mechanically direct injected engines. Both displacements use the Stanadyne DB-2 injection pump fed by a cam-driven lift pump.
The 1KZ-TE also adopts the electronically controlled fuel injection, ETCS-i (Electronic throttle control System - intelligent) technology which is similar in basic construction to a modern gasoline injector, although using considerably higher injection pressures, it is an indirect injection engine which gives it a significant efficiency and ...
The PSA XUD is a diesel engine designed and built by PSA — Peugeot and Citroën.It is an Indirect injection (IDI) engine, that uses a version of the Ricardo Consulting Engineers Ricardo Comet V prechamber cylinder head design. [1]
