Which Corolla model features a four-cylinder engine?
2 Answers
The 2021 Corolla models equipped with a 1.2-liter turbocharged engine and a 1.8-liter hybrid engine are four-cylinder engines. Power specifications: The 1.2-liter turbocharged engine delivers 116 horsepower and a maximum torque of 185 Nm, while the 1.8-liter naturally aspirated engine produces a maximum power of 72 kW and a maximum torque of 142 Nm. These engines are paired with a CVT transmission and a six-speed manual transmission, respectively. Exterior dimensions: The 2021 Corolla measures 4635 mm in length, 1780 mm in width, and 1435 mm in height, with a wheelbase of 2700 mm. It has a fuel tank capacity of 50 liters and a curb weight of 1290 kg. Additionally, here are some daily maintenance tips for the Corolla engine: Use lubricating oil of the appropriate quality grade. For gasoline engines, select SD--SF grade gasoline engine oil based on the additional equipment in the intake and exhaust systems and usage conditions. For diesel engines, choose CB--CD grade diesel engine oil according to mechanical load, ensuring the standard meets or exceeds the manufacturer's requirements. Regularly change the oil and oil filter. The quality of any lubricating oil will degrade over time. After a certain mileage, its performance deteriorates, leading to various engine issues. To prevent malfunctions, change the oil regularly based on usage conditions and maintain an appropriate oil level. When oil passes through the fine pores of the filter, solid particles and viscous substances accumulate in the filter. If the filter becomes clogged and oil cannot pass through, it may rupture the filter or open the safety valve, allowing oil to bypass the filter and carry contaminants back to the lubrication areas, accelerating engine wear and increasing internal pollution. Periodically clean the crankcase. During engine operation, high-pressure unburned gases, acids, moisture, sulfur, and nitrogen oxides from the combustion chamber enter the crankcase through the gap between the piston rings and cylinder walls. These mix with metal particles from component wear to form sludge. In small amounts, sludge remains suspended in the oil; in large amounts, it precipitates, clogging filters and oil passages, making engine lubrication difficult and causing wear. Regularly use a radiator cleaner to flush the radiator. Removing rust and scale not only ensures proper engine operation but also extends the lifespan of both the radiator and the engine.
I've been driving a Corolla for several years. The gasoline engines in this car are basically all four-cylinder, such as the 1.2T turbocharged version or the classic 1.8L naturally aspirated model. Since the Corolla from the 1990s, it has consistently used four-cylinder engines, which are stable and reliable, unlike some three-cylinder engines that vibrate annoyingly. Daily commuting is particularly easy, and fuel consumption is well controlled, averaging around 6-7 liters per 100 kilometers. Maintenance is also simple; just go to a small shop for an oil and filter change, costing about two to three hundred yuan each time. If buying a used car, I recommend looking for an older 1.6L four-cylinder model for its high cost-effectiveness. Overall, the Corolla's adherence to four-cylinder engines is to ensure driving smoothness and durability.
