Crankcase dilution occurs when the fuel oil from the engine gets into the lube oil of the engine. This can be caused by the walls being wetted due to the fuel condensing in the cylinder. If the engine is cold, or there is an excess amount of cooling around the cylinder, [ 1 ] the fuel oil will condense and have a higher chance to end up in the ...
The LAU is GM's new code for the LP9 Turbo engine, its usage starting with the 2010 Cadillac SRX. [1] In 2011, production of the Cadillac SRX with the LAU engine ceased, but the engine remained in use in the Saab 9-4X until 2012, when production of that model came to an end. [2] [3] Applications:
Second big problem: GM's cost-cutters decided not to fit a water separator. Unlike gasoline, diesel fuel is subject to water condensation – hence the need for a water separator. Without one, water in the fuel becomes water in the engine, where it can rust either the cylinders or the complicated mechanical fuel injection pump.
The Northstar engine is a family of high-performance 90° V engines produced by General Motors between 1993 and 2011. Regarded as GM's most technically complex engine, the original double overhead cam, four valve per cylinder, aluminum block/aluminum head V8 design was developed by Oldsmobile R&D, [citation needed] but is most associated with Cadillac's Northstar series.
The Cadillac SRX is a mid-size luxury SUV and compact luxury crossover SUV (CUV) manufactured and marketed by Cadillac over two generations: the first generation as a five-door, three-row, seven-passenger CUV (2003–2009), and the second generation as a five-door, two-row, five-passenger CUV (2010–2016) – the latter becoming Cadillac's best selling model in the United States.
The exception being the 1997 Calibras, which due to unavailability of C25XE engine blocks, were produced using the X25XE block but without modifications to the top end of the engine, and without addition of EGR. The X25XE also benefitted from a higher-volume oil pump. Firing order is 1-2-3-4-5-6. The breakdown of the engine name [1] is as follows:
The GM Ecotec engine, also known by its codename L850, is a family of all-aluminium inline-four engines, displacing between 1.2 and 2.5 litres.Confusingly, the Ecotec name was also applied to both the Buick V6 Engine when used in Holden Vehicles, as well as the final DOHC derivatives of the previous GM Family II engine; the architecture was substantially re-engineered for this new Ecotec ...
When nitrogen oxide (NO x) from the exhaust gases enters the catalyst, it is then selectively reduced to nitrogen and water. From 2013, this engine replaced the 1.7 L CDTI as well as lower-powered variants of the 2.0 L CDTI Ecotec 110 and 130 PS (81 and 96 kW; 108 and 128 hp) engines in Opel cars, and also superseded the 1.3 L CDTI engines in ...
