Engine type

4 CYLINDER - BOXER
What engine is the 4 cylinder boxer: the boxer-four is an engine where each pair
of opposed pistons moves inwards and outwards at the same time in two banks of
cylinders lying on opposite sides of a common crankshaft, named laso flat-four
or opposed-four.

What is the 4 cylinder boxer displacement: it is in a range between 1350 cc and
3000 cc in recent model line up powertrain.

How much is the power of the 4 cylinders boxer: the power of the 4 cylinders is
in a range from 98bhp to 365 bhp.Which cars use 4 cylinder boxer engine: 4 boxer is used by Porsche and Subaru but it has a strong heritage in powertrain production as have been used in cars by Volkswagen on the original iconic Beetle and Alfa Romeo.

The advantages of the boxer-four layout are perfect secondary vibration (resulting in minimal vibration), low centre of gravity and a short engine length. The layout also lends itself to efficient air cooling with the airflow being evenly distributed across the four cylinders. The downsides of boxer-four engines (compared with inline-four engines) are extra width, higher costs due to two cylinder heads instead of one and the long exhaust manifold required to achieve evenly spaced exhaust pulses.

The typical firing order for a boxer-four engine is for the left bank of cylinders to ignite one after another, followed by the right bank of cylinders with the firing interval evenly spaced at 180 degrees. The exhausts manifold from the two cylinders on each bank were merged and in result uneven exhaust pulses causing a characteristic "flat-four burble" exhaust sound as on Porsche 982 and 718 series with boxer 4.

The engine fires once every 180 degrees crankshaft angle (720 degrees divided by 4 = 180 degrees) and other common firing configuration (such as used by Subaru since the mid-2000s) is to pair the cylinders, with a firing interval of 360 degrees, in order to optimise the exhaust pulses. This configuration requires long exhaust manifolds to pair the cylinders on opposite banks and results in a less distinctive exhaust sound.
