General Motors is seriously looking into oil burners, with it’s latest move to buy 50% of Italian diesel engine maker VM Motori.

VM Motori and GM have jointly developed a 2.9 litre V6 turbodiesel engine for the upcoming European market 2009 Cadillac CTS (shown above). The engine will be designed, developed, tested, and built at VM Motori’s plant in Cento, Italy.

This 2,935cc DOHC 60-degree V6 turbodiesel engine makes 250 horsepower and a nice 550Nm of torque from 2,000rpm, and is flexible in it’s possible applications – both longitudinal or transverse layouts are possible, as well installed in both two wheel drive or four wheel drive cars.

Fuel economy is boosted using high-speed, piezo-resistive cylinder pressure sensors that are integrated within the engine glow plugs which read combustion data in real time and enables instantaneous fine-tuning of the fuel injection process.

Fuel injection is via a high pressure common-rail system with piezo injectors that can do up to 2,000 bar injection pressure. The turbocharger is mounted smack in the middle of the two cylinder banks, ensuring turbo piping is kept to a minimum length.
