How many cylinders does the BMW 730Li have?
1 Answers
BMW 7 Series 730Li is a four-cylinder car, while BMW 7 Series 740Li is a six-cylinder car. Differences in cylinder count: Generally, under the same displacement, the more cylinders there are, the smaller the cylinder bore. Therefore, under the same displacement, a three-cylinder engine has a larger bore than a four-cylinder engine. There are differences in power and fuel consumption: compared to a three-cylinder engine, a four-cylinder engine offers better power, faster acceleration, and more stable body control, but it also consumes slightly more fuel. Structurally, a three-cylinder engine has one fewer cylinder than a four-cylinder engine, along with corresponding reductions in the ignition system, fuel supply system, connecting rods and crankshaft, and camshaft components. Thus, a three-cylinder engine is structurally simpler than a four-cylinder engine. Engine cylinder classification: Currently, engines on the market are generally categorized into L4 (inline four-cylinder), H4 (horizontally opposed four-cylinder), V6 (V-type six-cylinder), W12 (W-type twelve-cylinder), etc. Some of these can be directly identified from the rear badge of the car, such as the Crown's 2.5V6, etc. For ordinary family cars, three-, four-, and six-cylinder engines are the most common.
