The 1990 Ford 7.3L diesel engine is a turbocharged, direct-injection, V8 engine. It has a displacement of 7.3 liters (445 cubic inches) and produces 185 horsepower and 360 lb-ft of torque. The engine is used in a variety of Ford trucks and vans, including the F-250, F-350, and E-350.
Operation
The 7.3L diesel engine operates on a four-stroke cycle. The four strokes are:
1. Intake stroke: The intake valve opens and the piston moves down the cylinder, drawing air into the cylinder.
2. Compression stroke: The intake valve closes and the piston moves up the cylinder, compressing the air.
3. Power stroke: The fuel injector sprays diesel fuel into the cylinder and the spark plug ignites the fuel. The burning fuel creates pressure that forces the piston down the cylinder.
4. Exhaust stroke: The exhaust valve opens and the piston moves up the cylinder, pushing the exhaust gases out of the cylinder.
Turbocharger
The turbocharger is a device that uses the exhaust gases from the engine to drive a turbine. The turbine compresses the air that is drawn into the engine, which increases the air density and allows the engine to produce more power.
Direct injection
Direct injection is a fuel injection system that sprays fuel directly into the cylinder. This is in contrast to port injection, which sprays fuel into the intake ports. Direct injection allows for more precise control of the fuel噴射and results in better fuel economy and emissions.
V8 engine
A V8 engine is an engine with eight cylinders arranged in a V-shape. The V8 engine is a popular choice for trucks and vans because it produces a lot of power and torque.
Applications
The 7.3L diesel engine is used in a variety of Ford trucks and vans, including:
* Ford F-250
* Ford F-350
* Ford E-350
* Ford Excursion
The 7.3L diesel engine is also used in some industrial applications, such as generators and construction equipment.
