1.8 LITER ECOTEC, 4-CYL, 110 C.I.D., GM ENGINE

As part of GM's small-displacement, power-dense four-cylinder engines, the Ecotec 1.8L is helping GM deliver more efficient yet fun-to-drive vehicles. It delivers an excellent balance of performance and efficiency. This compact inline four-cylinder engine combines competitive output, with sophisticated technologies such as dual continuous variable cam phasing (DCVCP), variable-geometry intake manifold, electronically controlled thermostat, engine oil cooler, with low maintenance, low emissions and outstanding fuel economy.

The LWE-code version of the LUW adds Secondary Air Injection, which adds fresh air to the exhaust stream for a more complete combustion of the exhaust gases – to enable PZEV (partial zero-emissions vehicle) status in California and Northeast states that require enhanced emissions.
