Chevrolet has just unveiled its new pickup truck – the 2012 Colorado. Alongside this announcement, the US automaker will debut a new global family of turbo-diesel four-cylinder engines.
These two new diesel engines are available in two displacements – one is the 2.5 Liter rated at 150 horsepower (110 kW) and 258 lb.-ft. of torque (350 Nm), and the second one, the 2.8L turbo-diesel rated at 180 horsepower (132 kW) and 346 lb.-ft. of torque (470 Nm) with an available six-speed automatic transmission.
Features such as hydraulic valve lash adjusters reduce maintenance costs by eliminating the need for periodic adjustments, while quick-start glow plugs promote fast engine starting in cold climates.
Additional highlights include:
? Iron cylinder block and aluminum DOHC cylinder head
? Proven common rail fuel system
? Electronic throttle valve that helps reduce emissions
? Cooled exhaust gas recirculation for enhanced performance and lower emissions
? Laminated steel oil pan with upper aluminum section that balances engine rigidity and quietness.
The engines meet Brazil’s stringent emissions requirements without the need for a particulate filter, which helps reduce the Colorado’s production cost.
A modular design of the basic architecture enables easier transition between versions and reduces production costs. The 2.8L and 2.5L use the same cylinder block and cylinder head and share many other components.
The production if these engines will start in September in Thailand.
