The engine design of the 7AFE engine is similar to that of the 4AFE engine, except that its cylinder-piston group is larger. It also features two-piece steel or aluminum-alloy oil pans. Both the pistons and the crankshaft are supported by 5 main bearings. The connecting rods are also supported by crankshaft drills. The order of the cylinders in the 7AFE engine is 1-3-4-2-2.
The 7AFE engine is the largest production A-series engine. It was manufactured from 1993 until 2002. Its cylinder bore and stroke are 81 mm and 85.5 mm, and it features a 4-valve DOHC narrow-valve angle. The engine also uses the slave-cam concept of the 4A-FE engine.
The 7AFE engine was developed by Japanese engineers in 1993. This engine produces more power than its predecessor, the 5A-FE engine. It also uses a lean-burn fuel mixture that is more efficient for the environment. Its working volume is 1.8 liters, and 120 horsepower is an impressive figure for a power plant of this volume. The low-gearing ratio and low crankshaft speed also contribute to low fuel consumption.
Toyota’s 7AFE engine is a common type of engine in the popular Corolla and Celica models. However, it is essential to make sure that you have the correct type of fuel when filling the engine. Using the wrong type of fuel can damage the engine.
There are several differences between the 7aFE engine and its EFI-S version. The 7A engine has a lean burn design, which produces a high amount of torque at low rpms. The STD engine has a slightly higher peak torque at 157 Nm, and the 3S-FE has a higher peak torque at higher rpms. The EFI-S version is more energy efficient than its predecessor.
The 7AFE engine was produced from 1990 until 2002, and the first generation was built for the Canadian market. This engine produced 115 horsepower at 5,600 rpm and 149 lb-ft of torque at 2800 rpm. In addition, there was a special version for the United States that was produced from 1995 to 1997. This engine was also produced in Indonesia and Russia. Its main differences were an improved crankshaft and oil return system, allowing it to produce more power at lower rpms.
The 7AFE engine used electronically-controlled multi-point fuel injection. Intake air volume was detected by a manifold absolute pressure sensor, which controlled ignition timing. It also allowed the ignition timing to be retarded to suppress knocking. Its pentroof-type combustion chambers had 9.5:1 compression ratio. Toyota recommended premium unleaded petrol for this engine and specified Caltex Havoline Formula 3 engine oil for it.
The 7AFE engine is a 1.8-litre petrol engine, and the most common application is the Corolla 7th-generation. It is also used in the Celica 6th-generation at base ST trim, and in the Geo Prizm. Its strongest output is 16 kgf-m at 4400 rpm, and its compression ratio is 9.5. In addition, the 7AFE engine is now used in the 8th-generation Corolla.
Toyota Crown Premium engine
The Toyota Crown Premium is a luxury trim for the Toyota Crown. It is built on a hybrid powertrain. The Platinum model gets a 2.4-litre turbocharged engine paired with an electric motor to deliver 340 horsepower. The XLE and Limited trims have a 2.5-litre four-cylinder engine and three electric motors to produce 236 horsepower. The automatic transmission is available in four and five-speed options. There is also all-wheel drive.
The 7AFE engine was produced between 1990 and 2002. The first generation was produced for the Canadian market and produced 105 horsepower and 149 Nm of torque. The United States market saw a special version of the 7AFE engine in 1995 and 1997. The Russian and Indonesian versions were the most powerful versions of this engine.
The Toyota Crown comes standard with a 12.3-inch infotainment touchscreen with the latest software interface. It also supports Apple CarPlay and Android Auto. These platforms connect to smartphones wirelessly. The car also offers USB-C ports and onboard Wi-Fi. The interior features a leather steering wheel, a dual-zone climate control system, leather seats, and digital gauge clusters.
The 7AFE engine is similar to the 4A-FE engine, but has some differences. The cylinders have slightly different sizes. In addition, the 7AFE engine has a knock sensor and a DIS-2 contactless ignition system.
