Your motorcycle engine works much in the same way as a car or truck's engine does. When it comes to your BMW Motorrad engine, there are many parts that make up the whole. These include cylinder heads, cylinder blocks, camshafts, pistons, connecting rods, crankshafts, rocker arms, valves, spark plugs, cooling systems, batteries, air filters, and -- depending on the age of your bike -- either carburetors or fuel injectors.
How they work is simple. Pistons move up and down inside the cylinder block, propelled by small explosions of the air-and-fuel mixture. Those explosions occur thanks to a spark that ignites the mix. The valves open and lose to allow the mixture to enter the combustion chamber as needed. The pumping of the pistons turns the crankshaft, which converts that vertical motion into rotary motion. The rotary motion is then sent to your motorcycle's rear wheel. Meanwhile, the cooling system keeps the engine at an optimal temperature,
Types of Motorcycle Engines
Motorcycle engines are classified by any of three factors: the number of cylinders, the capacity of the combustion chamber, or the number of strokes in the power cycle. To go into more detail, they can have anywhere from one to six cylinders. The most popular design these days is a four-cylinder engine, since it runs smoother and delivers higher RPMs than the typical two-cylinder powerplant. Capacity can range from 50 cubic centimeters (cc) to 1500 cc. Put plainly, the smaller the size the less power produced.
How to Spot Faulty Engine Components
Even the best engine components can eventually go bad, whether due to wear-and-tear, poor maintenance, or age. Signs of trouble include:
Reduced power output
Worsening fuel economy
Increased exhaust emissions
The engine keeps running after you turn it off
