Are Three-Cylinder Cars Common Abroad?
1 Answers
Three-cylinder cars are not common abroad. Advantages of three-cylinder cars: The turbocharging advantage is prominent. With the fewest cylinders, three-cylinder engines reduce mechanical friction during movement, improve thermal efficiency, and offer better fuel economy while reducing exhaust emissions. They also lighten the vehicle's curb weight, aligning with lightweight design principles. Disadvantages of three-cylinder cars: Three-cylinder engines may experience intermittent power delivery during operation. Additionally, the inherent imbalance of moments in three-cylinder engines can lead to accelerated wear of engine crankshaft bearings and reduced lifespan. Future trends of three-cylinder cars: Vehicles equipped with three-cylinder engines currently account for a very low percentage in the market. Not all automakers compromise on vehicle quality under pressure, so three-cylinder engines with poor NVH (Noise, Vibration, and Harshness) performance will not become mainstream. Moreover, the era of internal combustion engines is destined to end, with electric motors gradually replacing them within the next 5 to 10 years. As range extenders for plug-in hybrid vehicles (including range-extended electric vehicles), three-cylinder engines will also be replaced by hybrid electric piston thermal engines currently under development. This technological regression is merely a phenomenon occurring at a specific juncture, and such engines will be quickly phased out.
