Whereas ordinary diesel direct fuel-injection systems have to build up pressure anew for each and every injection cycle, the new common rail line engines maintain constant pressure regardless of the injection sequence. This pressure then remains permanently available throughout the fuel line. The engine's electronic timing regulates injection pressure according to engine speed and load. The electronic control unit ECU modifies injection pressure precisely and as needed, based on data obtained from sensors on the cam and crankshafts.
The most dominant diesel engine in the Indian market today is the 1. The Renault K9K 1. Honda, however, has ruled out sharing its new 1. Honda diesel is the most fuel efficient All these three engines have one thing in common — they are incredibly fuel efficient, with the Honda iDtec walking away with the honors in fuel economy at The Renault-Nissan K9K does Honda Amaze diesel road test and review — an amazing package Honda 1.
Fiat multijet is the most compact engine In terms of size, the Fiat 1. The Renault-Nissan K9K 1. Figures from its application in Dacia vehicles show it has a service ready weight of Kg, slightly more than the 1.
It is, however, larger in capacity. Honda has used thinner walls for the cylinder block and reduced the size of the water pump when compared to the larger 1.
However, this engine has the potential to boost this power figure to around bhp and torque by at least 50 Nm using a variable geometry turbo, which it may in the next-generation Honda City. The Fiat multijet churns out its lowest torque and power figures in the Premier Rio and the highest in the Fiat Linea.
Performance modifications for your diesel car There is no clear winner here on which is the best engine of the lot. The K9K is endearing because of its simplicity, the Honda because of its precision engineering, while the 1.
All three engines are reliable diesels in their own right.Oct 27, · Higher efficiency: turbochargers run off energy that is typically lost in naturally-aspirated and supercharged engines (exhaust gases), thus the recovery of this energy improves the overall Reviews: Turbocharging: Key technology for high-performance engines Turbocharger development and production at MTU Turbocharging is an integral component of the engine design concept.
It shapes the character - diesel particulates or nitrogen oxides during the. Vs CRDI In Diesel Engine Engineering Essay. Print Reference this. it is utilised in gasoline direct injection engine technology. PRINCIPLES. While the CRDI engine expensive over time.
Turbocharger Technology Vs CRDI In Diesel Engine - crdi engine working principle pris pdfcrdi engine working principle pris - unionsquareventures. A turbocharger compresses the air so that more oxygen flows into the combustion chamber.
In this way, more fuel is burned and the power output of the engine increases accordingly. The turbocharger is driven by exhaust gas, which makes turbocharged diesel engines very efficient.
MTU develops this key technology for high-performance engines in-house. Jan 26, · The Diesel Variable Geometry Turbo or turbocharger is the answer to today's demanding diesel engine requirements. Turbo or turbine air induction does not mix with EGR and modern clean diesel requirements. See how a variable geometry turbocharger differs from normal turbos.
Variable geometry turbos or VGTs are here to stay. The turbo is a VGT turbo with overhead intercooler (the intercooler is placed in the engine head to avoid pumping looses) The engine uses dual overhead cams with 4 valves per cylinder,and the engine is also less in weight.
