Which is better direct injection or indirect injection?
Indirect injection in an internal combustion engine is fuel injection where fuel is not directly injected into the combustion chamber. Direct injection allows the fuel to be precisely metered into the combustion chamber under high pressure which can lead to greater power, fuel efficiency. …
What is the difference between direct injection and indirect injection diesel engines?
A direct injection diesel has the injector “directly” in the combustion chamber of the cylinder. An Indirect injection engine has a separate little “pre-combustion” chamber thats connected to the main cylinder by a short little passage. The explosion happens in the little pre-chamber and then travels into the cylinder.
What is the difference between a di and IDI diesel engine?
Lower injection pressures also mean IDI injectors will outlast DI injectors. Direct injection diesels are favored due to their efficiency, performance potential, and cleaner exhaust emissions. IDI diesels, however, have built a reputation of reliability and their ease of service/repair is alluring nonetheless. What does Google know about me?
Is a Cummins a direct injection engine?
All versions of the Power Stroke, Cummins, and Duramax diesel models are direct injection diesels, where as International’s earlier 6.9L/7.3L and General Motor’s 6.2L/6.5L motors had pre-chambers and therefore fall under the category of IDI’s. IDI diesel engines utilize a pre-combustion chamber, generally referred to as a pre-chamber.
Is the Duramax a direct injection engine?
The duramax is called a “direct injection” by many. Aren’t all diesel engines direct injection? I think a common rail high presure is more correct. These injectors are triggered electronically. (hence the common rail), and wiring to injectors. Older diesels had individual lines running from the injector pump.?
