The Mazda B-Series engine, specifically model 300-66126B, was produced between 1989 and 1993. This is a 2.6-liter, four-cylinder engine that was a popular choice for various Mazda vehicles during this period.

The engine block is made of aluminum alloy, which contributes to its lightweight yet robust construction. The cylinder bore is 86.0 mm, and the stroke length is 93.2 mm, resulting in a total displacement of 2,583 cc. The compression ratio is 9.5:1, providing a good balance between power and fuel efficiency.

The engine features an SOHC (Single Overhead Camshaft) design with four valves per cylinder. The intake valves are actuated by a single camshaft located above the cylinder heads, while the exhaust valves are operated by a separate camshaft located below the cylinder heads. This design allows for better valve control and more efficient combustion.

The engine is also equipped with a multi-point fuel injection system, which delivers fuel directly into the intake ports for more precise and efficient combustion. The fuel injection system uses a Bosch electronic control unit (ECU) to manage the fuel delivery and ignition timing.

The engine block is equipped with a cast-iron cylinder liner, which provides durability and resistance to wear. The pistons are made of aluminum alloy, and they feature a compression ring and two oil control rings. The connecting rods are made of forged steel for added strength and durability.

The engine also includes a water pump, thermostat, and cooling system to regulate engine temperature. The oil system includes an oil pump, oil filter, and oil cooler to ensure proper lubrication and cooling of the engine components.

The Mazda 300-66126B engine is known for its reliability, fuel efficiency, and power output. It produces approximately 115 horsepower at 5,500 rpm and 142 lb-ft of torque at 3,500 rpm. This engine is a popular choice for those seeking a powerful yet fuel-efficient engine for their Mazda vehicle.
