Diesel engine technology has advanced by seeming light-years over the last decade or so. Though diesel have always been very fuel efficient, met stringent emissions regulations and expectations of performance. Today, certain car manufacturers choose diesel as one of the engine option for their sport car model.
Old Diesel engine, the fuel pump and injectors on early diesels were completely mechanical. Although ruggedly built, the working pressure of the fuel system were not high enough to render a sustained and well-defined spray pattern of fuel and this resulted hesitation of power but emitting lots of black smoke. Unlike gasoline engines, diesel engines does not have spark plugs to ignite, but relying on heat generated by intense compression of air in the combustion chambers.
New Diesel engine, advances in fuel delivery and engine management systems have allowed the new generation of diesel engines to produce more power, quieter, less emission and impressive fuel economy. It’s the high pressure fuel rail and computer controlled fuel injectors that make all the difference. In common rail system, the fuel pump charges the fuel rail to a pressure of up to 26,000psi. Under the control of onboard computer, the fuel quantity and pressure accumulated is adjusted according to the driving condition.
The diesel engine has the highest thermal efficiency of any regular internal or external combustion engine due to its very high compression ratio. Therefore, diesel engine is necessary to coordinate with the Air Management System, Fuel Management System and Voltage Management System in order to maximize the output. This three management system is playing an important role for the diesel engine, because it will directly influence the performance of the engine especially for the older type of engine. Thus, Qmax Management System is a good enhancement product in any circumstances.
