Cylinder displacement is, first and foremost, the main ingredient behind good horsepower and efficiency. This is the measurement of volume of a cylinder through its diameter. A larger cylinder holds more air and fuel, thus producing more power. If the cylinder is longer as well, it is able to maintain a more constant burn of fuel and air in the cylinder as the piston travels up and down, producing constant power with less vibration as well.

A well-made, bueatiful engine known as the CUB Cadet is a perfect blend of efficiency, torque, and horsepower. There are many options for you to choose from when it comes to a lawnmower engine, so that's why we've included a list below of the top engine companies. It'll give you no excuse to have a low quality, inefficient engine that is powered by one of the below engine companies. You can view the full engine list by checking out our engine comparison review. The article compares the key differences between the many lawnmower engine brands and is an essential read if you want to ensure your engine is the best it could be.

Honda Engines

You can never go wrong with a Honda engine. HP is probably the most important rating with lawn mowers. If you are cutting lawns for friends and family, then you need a lawn mower that is light weight. On the other hand, if you mow professionaly, you are looking at pushing 1,000 feet per minute in a 30 degree incline. The larger engine will have a higher inch per minute.Lift kit is important for higher areas where the grass is greener. A larger engine will eat up grades better.

How a Lawn Mower Engine works

You may be surprised that a lawn mower engine is not that different from a car engine. The main difference is that air-cooled cars use a liquid coolant, while lawn mowers have air-cooled engines. A four-stroke engine is used almost exclusively in lawn mowers and small engines.

The engine starves itself of air, and then is shot with a high-pressure mixture of fuel and air. The mixture burns rapidly and then cools. The engine pushes the cooled mixture out of the cylinder, and pulls in more fuel and air.

It shifts back and forth, and burns fuel in a very inefficient way. The engine must repeatedly choke itself in order to achieve the desired operation. The air-cooled engines used in lawn mowers are notoriously inefficient and pollute much more than a car engine.

In most cases, a car’s motor is over 50 times more energy efficient than a lawn mower’s motor. The engine in a lawn mower runs rough, producing an extremely loud sound, and has a very short lifespan because of the harsh environment in which it operates.

Performance and Longevity

When it comes to the engine, there are a few main things to consider. It needs to be highly reliable and easy enough to fix when something goes wrong. It should also have high power and torque to make it easier to use and cause less strain on the user. The engine needs to be tolerant of variations in fuel so that you don’t have problems with the mower clogging or misfiring.

The best engine for a mower is a relatively new innovation, called the four-cycle engine. These engines have been in use for a while now but are only really taking off in popularity in the past decade.

How the Engine Works

A four-cycle engine works by mixing the gasoline and oil together and then running an electric spark across the mixture to get it started. Once it’s running, it’ll operate like a two-cycle engine. The real advantage of these engines is that, if something goes wrong with it, it’s a lot easier to get it back into working order. The spark plug is removed and the carburetor cleaned, and then it’s ready to go.
