BMW turns to diesel cars to rev up sales

[ALBundy]

A few points to add on the advantage of diesel engines.

Diesel engines on average last at least twice as long compared to its petrol counterpart largely due to less moving parts, stronger internals (most are forged) and the fuel itself acts like lubricant, unlike petrol.

And where Efficient Dynamics is concerned, it is more than just the advanced diesel or High Precision Injection (HPI) engines , brake energy regeneration, lightweight construction with extensive aluminium being used, aerodynamics (example; flat under surface to improve air flow) and etc are some of the notable technology employed for BMW to stay ahead of the competitors.:top:

How is the character of diesel engine? I mean when push hard. Torque band and etc?

Cheers

sham..memang mabeles!

First of all, diesel engines are based on Rudolph Diesel gas cycle. That means it is a compression engine, and there is no spark plugs.

Mixture of diesel mist and air is compressed to high pressure where the mixture becomes hot and ignite by itself! As a result, there is plenty of torque generated...and the diesel clatter which is actually the sound of the mini explosion! When pushed hard, it does move pretty fast. Try one for yourself and judge the performance, you will be pleasantly surprise with the drivability

Generally, diesel engines have a lower rev limit (compression engine) and less revvy compared to a petrol engine. That being said, the modern diesel are not far behind petrol engines in terms of fun factor, well diesel engines have won the last few 24 hours LeMans races!

The middle one is our N47 variant, at 1800 bar injector pressure, compression 16:1, boost pressure 2.55 bar

Sir, I always thought compression stroke on diesel engine only compresses the air and then fuel is injected a few degree BTDC

Yes you are right. To be more detailed, the diesel is injected in the last stage of compression

they probably got fed up waiting for the quality of diesel here to improve and instead said lets look at what is within their control and adjusted their car to suit...
