The New Mercedes-Benz 3-Cylinder Diesel Engine
For the joint project Smart For four and Mitsubishi Colt, Mercedes-Benz developed a 3-cylinder diesel engine derived from the A-Class 4-cylinder engine. This engine allows both high performance and low fuel consumption. The top version with 70 kW is the world’s most powerful three-cylinder passenger car diesel engine.
In mid-2000, Mitsubishi and Smart began a joint project to develop a four-seater compact car. Their combined efforts led to the idea of transforming a four-cylinder A-Class engine into a three-cylinder diesel engine and installing it in Smart and Mitsubishi compact cars. In addition to the cost benefits resulting from the newly created engine model series, the large individual displacement of a 1.5-litre three-cylinder diesel engine leads to better thermodynamic ratios compared to the four-cylinder engine with the same displacement. As a result, a completely new three-cylinder in-line engine producing 50 and 70 kW of power was developed for the diesel version of the Smart Forfour and the Mitsubishi Colt.
The Concept
The stringent guidelines for exhaust emission level Euro 4, as well as fuel consumption, performance, comfort and low manufacturing costs led to a solution with the following characteristics:
- transverse, front installation
- unified combustion chamber as in other Mercedes-Benz CDI engines going on the market in 2004
- four-valve design with built camshafts and roller cam followers
- swirl generation through tangential and spiral intake with infinitely variable swirl control
- exhaust gas turbocharging
- cooled exhaust gas recirculation
- second-generation common rail fuel-injection system with 1600 bar and solenoid valve injectors
- balancer shaft
- dual-mass flywheel
- engine (transmission) control unit (with Green Oak processor)
- powertrain designed for peak pressures of up to 180 bar
- engine mounting as roll axis system.
