The M.A.N. M-Combustion System in the Passenger Car Diesel Engine 770434

This paper discusses the use of the direct-injection “M” combustion system in a small high-speed Diesel engine. Experimental and test results are given for a passenger car whose 60-HP (DIN) four-cylinder engine with 2.2 litres (134 in3) displacement was converted for the “M” system. The combustion system which is being widely used in commercial vehicle engines possesses advantageous features which make it attractive for use in passenger cars on account of its inherently low fuel consumption and noise level. The author describes modifications of the combustion process which enable substantial improvements to be achieved in exhaust gas quality.
