GM’s new diesel engine design cuts cost and weight
Diesel cars are going to be a big power in USA also by 2010. And thta’s because a diesel engine can be about 25% more fuel-efficient than gasoline engines.
And GM wants to be prepared for this. This is why by 2009 the company wants to create a radical new engine. "In today’s auto industry, you can’t afford to develop an average anything. You can’t set your goals that you want to be like everybody else."
GM’s new engine’s design, design, air enters the engine through ports in the outer portion of each cylinder head. The exhaust gases then exit inward between the cylinder heads and directly into a turbocharger. That eliminates numerous parts, saves space and lets the engine make more efficient use of heat. All of that improves fuel economy and performance, reduces noise and lowers emissions.
Another good news is that the new design could shave $350 to $600 off the cost of producing the engine.
The compact design also solved a space problem. GM wanted a V-8 diesel that could fit in the same space as the small-block V-8 gasoline engines in the Chevrolet Silverado/GMC Sierra pickups, and in the Chevrolet Tahoe/GMC Yukon SUVs. Narrower than a regular diesel of the same displacement, the new engine fit.
The top brass approved the new diesel engine for GM’s light-duty trucks. It is scheduled for production in 2009 at a revamped plant in Tonawanda, N.Y.
