Why is the Subaru boxer engine so good?

Subaru ‘Boxer’ engines also feature all aluminium construction of the crankcase and cylinder heads that also significantly contributes to weight reduction. This not only improves the power to weight ratio and therefore driving and environmental performance but also again helps handling and stability.

How long do Subaru boxer engines last?

While results will vary and the big variable is always how well the car has been maintained, what I can tell you is a Subaru is capable of going 300,000 miles. And if you are a regular maintenance type of owner you should expect to get that type of mileage out of it.

How big is the boxer engine in a Subaru?

When petrol engines are converted to diesel, strengthening of the engine block usually makes the engine bigger and heavier.

Why was the kontra engine called a boxer engine?

Boxer engine. He called it the kontra engine, as the action of each side opposed the action of the other. This design has since been called the “boxer” engine because each pair of pistons moves in and out together, rather like the gloves of a boxer. The boxer engine has pairs of pistons reaching TDC simultaneously.

What’s the firing order of a boxer engine?

He starts by discussing firing order, pointing out that a boxer engine fires in the sequence 1-3-2-4, while an inline-four’s combustion reactions happen in the order 1-3-4-2 (note that the cylinders are counted from the front-end accessory side to the rear flywheel side).
