The bare engine is the power machine of your car, literally converting energy, in the form of fuel, into movement, known as an internal combustion engine. When you buy a replacement bare engine you are buying an engine that is basically just a crankcase and cylinder head, not a complete full engine, which is why this is commonly referred to as a short block engine. This means you will be buying the case of the engine which houses the cylinders and components but does not include these parts.
The bare engine is built to be strong and solid. Usually made of steel, cast iron or aluminum, it is the crux of your car and needs to be in good condition and maintained well to do its job properly.
There are different types of engines so it is a good idea to make sure you know which type of engine you would like to buy. It is important to make sure that the type of bare engine you purchase is compatible with your car. Straight engines are a common type of engine and are lighter and more compact than other types of engine. Run with four cylinders which are all set in a straight line, this type of engine is usually the most economical to run and are generally cheaper to make than other types of engine. Another common engine type is a V Type engine. The V Type engine is usually used in high performance cars, such as racing cars offering high speed performance when needed. The length of the engine is shorter in a V Type and the cylinders are arranged at 90 degree angles from each other, differing to the straight cylinder arrangement in the straight engine. A boxer engine is usually fitted in the rear of the car, unlike most engines which are usually found under the bonnet. The boxer engine has two cylinder heads at opposite ends of the crankshaft. The boxer style engine has a low center of gravity so is stable and solid, and runs smoothly when the car is idling, but it is a lot wider than other engine types so can be tricky to fit into some small cars and also has a tendency to be noisier than other engine types. A diesel engine is different to other engine types in that it runs on diesel instead of petrol. Another major difference is a diesel engine doesn't need spark plugs because ignition of the engine happens by the fuel and air being compressed before it reaches the combustion chamber. A diesel engine is more fuel efficient than a petrol engine and tends to last much longer than other engine types.
You may need to replace your bare engine because your old engine has broken or maybe you are undertaking a project and wish to build a new engine or wanting a bare engine that performs better and is more fuel efficient. It is important to search for the right make, model and year of your car, as well as the type of engine that you require, to get the right bare engine for your car. If your engine needs replacing there are a number of things that could have gone wrong. It is often a cheaper option to replace your engine with a bare engine and use salvageable parts from the broken engine. You will have the option to buy a new bare engine or a used bare engine that has been salvaged and rebuilt from a car that has been in an accident or just an old car that is no longer on the road.
