It is also much quieter than an indirect injection diesel.

If no indirect injection is present, the engine hence needs to be fitted with this.

Fuel consumption is about 15-20% lower than indirect injection diesels.

See the development of the hot bulb engine and indirect injection for historical significance.

The engine was a traditional four cylinders diesel with indirect injection.

Just about any indirect injection diesel engine has the capacity to run on vegetable oil.

However, the latter is only possible when the engine has been foreseen with indirect injection.

Because their shape is more similar to those of current indirect injection engines, they are able to exploit all available power at high speeds.

This is especially the case with indirect injection engines, which are less thermally efficient.

If you drive an older indirect injection non emission controlled diesel.

In an indirect injection system the air moves fast, mixing the fuel and air.

Cylinder head of a small Kubota indirect injection diesel engine.

The 1.7 litre diesel was an indirect injection unit.

The indirect injection engine could be considered the latest development of these low speed hot bulb ignition engines.

Indirect injection with pre-combustion chambers provide smooth, quiet operation.

It is an indirect injection engine, naturally aspirated.

Both mechanical and electronic injection systems can be used in either direct or indirect injection configurations.

Fuel system - Distribution type jet pump (indirect injection)

This is called Indirect injection.

Due to the design of the combustion chambers in indirect injection engines, these are the best engines for use with vegetable oil.

Indirect injection engines are cheaper to build and it is easier to produce smooth, quiet-running vehicles with a simple mechanical system.

Later, more mainstream applications of fuel injection favored the less-expensive indirect injection methods.

The fuel system also utilizes indirect injection which made it quieter than mechanically direct injected engines.

This is somewhat offset due to indirect injection having a much higher compression ratio and typically having no emissions equipment.

Indirect injection diesels can still be found in the many ATV diesel applications.
