engine development

 The rotor and housing of a rotary engine from a Mazda RX-7: These parts replace the pistons, cylinders, valves, connecting rods and camshafts found in piston engines.
Like a piston engine, the rotary engine uses the pressure created when a combination of air and fuel is burned. In a piston engine, that pressure is contained in the cylinders and forces pistons to move back and forth. The connecting rods and crankshaft convert the reciprocating motion of the pistons into rotational motion that can be used to power a car.
In a rotary engine, the pressure of combustion is contained in a chamber formed by part of the housing and sealed in by one face of the triangular rotor, which is what the engine uses instead of pistons.

In tough economic times, manufacturers have to diversify, as well as work on their strengths. According to one German magazine, BMW has done just that, and is willing to supply its engines to competitive marques.

With BMW cleaning up International Engine of the Year awards in several categories, and for several years, it makes sense to profit from its experience in this field.

BMW’s head of development, Klaus Draeger, has been reported as saying that BMW is moving forward with plans to sell its engines to Mercedes, as well as other brands.

2.5 litre VM Motori engine

Built specifically to meet the latest Euro IV emissions legislation, the VM Motori R 425 DOHC is the cleanest diesel engine ever to beat at the very heart of a LTI taxi. Cleaner and greener with no compromise in economy or power.
Designed by Europe's leading diesel engine specialist specifically for the TX4, the high torque delivery at low speed means you can pull away from a standing start quickly and comfortably, a feature fundamental to taxi operation.

Supercharged LS9 Small Block V8 for the 2009 Chevrolet Corvette ZR1

 

 Incorporating the engineering experience already found in the Corvette Z06's LS7 engine and the new-for-2008 6.2L LS3 of the Corvette, GM Powertain is targeting 100 horsepower per litre for the LS9, or 620 horsepower (462 kW), and approximately 595 lb-ft of torque (807 Nm); final SAE-certified power levels will be available in early March 2008.

Will Dodge keep a 4-cylinder engine in the option list for the 2008 Dodge Caravan? If it does, this new 2.4-liter "world engine" (also found in the Dodge Caliber) will likely be the one.
