The 1991 Honda Accord EX uses a 2.2-liter inline-4 engine.
In the fourth-generation Accord (1989–1993), the EX trim adopted a 2.2-liter four-cylinder engine as its standard powerplant in most markets. There were two main variants of this engine across regions: a single-overhead-cam (SOHC) version and a dual-overhead-cam (DOHC) version. Exact engine codes and horsepower depend on market and emissions equipment, so checking the VIN or engine stamping will confirm the precise variant for a given car.
Engine configurations and performance
The 2.2-liter four-cylinder powered the 1991 Accord EX across several markets, serving as a reliable workhorse for daily driving in the early 1990s. Power figures vary by variant and transmission, but typical estimates fall within these ranges:
- SOHC 2.2L: roughly 125 horsepower, depending on year and emissions setup.
- DOHC 2.2L: roughly 140–150 horsepower, depending on market and equipment.
Despite the two variants, both share the same displacement and cylinder count, and were offered with either a manual or an automatic transmission in the U.S. market where applicable.
Engine identification and codes
Engine codes distinguish variants. In the United States, early 1991 Accords commonly used the 2.2L family, with specific codes like F22A1 or F22B1 depending on region and model year. To confirm the exact engine code for a particular car, consult the engine block stamping or the vehicle’s documentation that lists the engine code and VIN options.
Market differences and notes
While the core 2.2-liter four-cylinder remained the backbone of the EX, some markets saw small variations in tuning to meet local emissions and driver preferences. The presence of SOHC versus DOHC configurations typically corresponds to different trim levels and production runs within the 1991 model year.
Summary
In sum, the 1991 Honda Accord EX is equipped with a 2.2-liter inline-4 engine, with variants including both SOHC and DOHC designs. The exact horsepower and engine code depend on the market and the car’s emissions configuration, so checking the VIN or engine stamping provides the definitive identification.
