The 4 cylinder generates power at every degree rotation of the crankshaft whereas a 3 cylinder engine generates power at every degree rotation of the crankshaft of the engine. This difference in the power generation, timing and technique make the two engines differ drastically from each other based on performance, usage, fuel consumption and a lot more. A 3 cylinder engine has some advantages as well as some disadvantages which should be looked into before using one.
Although the difference seems to be negligible, the difference can be felt to someone who has driven or is used to driving a 4 cylinder. Due to the difference in the way the pistons are arranged in a 3 cylinder design, which brings in the delay of half a cycle between the power strokes. Not Refined: A 3 cylinder engine requires more work than a 4 cylinder engine due to the lower number of cylinders present. The 3 cylinders perform most of the work against the 4 cylinders which makes them a tad bit noisier than their 4 cylinder counterparts.
This is because both types are developed and designed to cater to different needs and have different consumers which they have to serve. If you are someone who is a power aficionado and if the performance of your vehicle ticks your preference list above the other aspects then go for a 4 cylinder vehicle which will suit your needs perfectly. At the end of the day, choosing a car will lie on your personal preferences rather than the brochures and manuals published by the manufacturers.

A turbocharger is a device that is used to boost the power of an engine. A four-cylinder engine with a turbocharger can produce as much power as a six-cylinder engine, but uses less fuel when driven gently. For more information, see How Turbochargers and Superchargers Work. Horsepower and torque measure the amount of power an engine develops, with horsepower being the most commonly-used measurement.
The difference between horsepower and torque is widely misunderstood and difficult to explain. Torque, which is measured in pound-feet lb-ft or ft-lbs , measures pulling power; when you step on the gas pedal and the seat pushes into your back, you are feeling torque.
Trucks need lots of torque to get their heavy loads moving. Horsepower is a function of torque and engine speed RPM , and indicates how much sustained work the car can do. Racing cars need high horsepower to maintain high speeds. Generally, bigger-displacement engines develop more torque, but small engines can spin faster, which increases their horsepower output.
A car with high horsepower but low torque may feel sluggish from a stop, but will feel stronger as the engine spins faster and faster.
A high-torque, low-hp engine will accelerate strongly from a stop, but will trail off as the engine speeds up until the transmission shifts gears. At other speeds, the engine develops less horsepower. The same goes for torque, although some engines especially those with turbochargers have a sustained peak-torque range, developing their rated torque between, say, 1, and 4, RPM.
The gas in your car causes a combustive event that pushes the piston to the crankshaft; the more cylinders there are, the more power your car can generate and the more power your engine has. Here are some of the main differences between 4 and 6 cylinder engine types. Automobiles might seem complicated, but by learning just a little bit about your car you can learn better ways to take care of it.
