Starting in 1990, Chevrolet offered a high-performance version of the Lumina, the Lumina Z34. It came standard with the FE3 sport suspension package, the 210 hp (157 kW; 213 PS) LQ1 V6 engine shared with the Lumina Euro 3.4 (sedan), the 5-speed Getrag 284 manual transmission, dual exhaust, and 4-wheel anti-lock brakes.
When the engine is cool or even at normal operating temperature, the fan clutch partially disengages the engine's mechanically driven radiator cooling fan, generally located at the front of the water pump and driven by a belt and pulley connected to the engine's crankshaft. This saves power, since the engine does not have to fully drive the fan.
The Chevrolet Lumina APV is a GM U-body vehicle, using the GMT199 platform designation. In contrast to the unibody design used by the Astro/Safari and the Van/Vandura, the Lumina APV chassis uses a chassis design similar to the Pontiac Fiero and Saturn SL , with a galvanized steel spaceframe supporting exterior body panels.
For water-cooled engines on aircraft and surface vehicles, waste heat is transferred from a closed loop of water pumped through the engine to the surrounding atmosphere by a radiator. Water has a higher heat capacity than air, and can thus move heat more quickly away from the engine, but a radiator and pumping system add weight, complexity, and ...
Water is inexpensive, non-toxic, and available over most of the earth's surface.Liquid cooling offers higher thermal conductivity than air cooling. Water has unusually high specific heat capacity among commonly available liquids at room temperature and atmospheric pressure allowing efficient heat transfer over distance with low rates of mass transfer.
The Trump transition team wants the incoming administration to drop a car-crash reporting requirement opposed by Elon Musk’s Tesla, according to a document seen by Reuters, a move that could ...
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 former could destroy the engine, while the latter would denigrate the engine's running characteristics and possibly deep-six the pump – which, in a mechanically-injected diesel, is an ...
