The Model A Ford engine is a classic engine that was produced from 1928 to 1931. It was the second huge success of the Ford Motor Company after the Model T. The Model A engine was a four-cylinder engine that had a displacement of 200.5 cubic inches. The engine was built with a cast iron block and head and had a maximum output of 40 horsepower. The Model A Ford engine was the first engine that Ford produced that featured a water pump and a pressurized cooling system. It was also the first engine that had a fuel pump, which was a significant improvement over the gravity-fed carburetor of the Model T. In this article, we will take a closer look at the Model A Ford engine and what makes it a unique and interesting piece of automotive history.
Design and Construction
The Model A Ford engine was designed with a L-head configuration. This meant that the valves were located in the block, and the spark plugs were located on the cylinder head. The engine was built with a three-main bearing crankshaft and had a bore and stroke of 3.75 inches by 4.00 inches. The engine had a compression ratio of 4.22:1 and used a Zenith one-barrel carburetor. The engine was cooled by a pressurized system that used a water pump to circulate coolant through the engine. The oiling system was a splash system that used a dipper in the oil pan to splash oil onto the moving parts of the engine.
The Model A Ford engine was built with a cast iron block and head. The block was cast as a single piece, and the head was bolted onto the block. The engine had a total of eight valves, with two valves per cylinder. The engine had a cast iron intake manifold and an exhaust manifold that was made of stamped steel. The engine was also equipped with a mechanical fuel pump that was mounted to the cylinder block.
Performance and Maintenance
The Model A Ford engine had a maximum output of 40 horsepower at 2200 rpm. The engine had a top speed of around 65 miles per hour and could accelerate from 0 to 60 miles per hour in around 30 seconds. The engine was designed to run on gasoline with an octane rating of 70 or higher. The engine was also designed to run on low-lead gasoline, which was a new type of fuel that was introduced in the late 1920s.
Maintenance of the Model A Ford engine was relatively simple. The engine required regular oil changes, and the oil filter needed to be cleaned or replaced periodically. The spark plugs needed to be checked and cleaned or replaced as necessary. The carburetor needed to be adjusted periodically to ensure that it was delivering the correct fuel mixture to the engine. The cooling system needed to be checked periodically for leaks or other issues, and the radiator needed to be flushed periodically to remove any buildup of sediment or rust.
Restoration and Collectibility
The Model A Ford engine is a popular engine among collectors and enthusiasts. Many Model A Fords have been restored to their original condition, including the engine. Restoring a Model A Ford engine can be a challenging but rewarding experience. The engine is relatively simple, which makes it easier to work on than more modern engines. However, finding parts for the engine can be challenging, as many parts are no longer in production.
Overall, the Model A Ford engine is a unique and interesting piece of automotive history. It was a significant improvement over the Model T engine and was the first engine that Ford produced that featured a water pump and a pressurized cooling system. The engine was simple, reliable, and relatively easy to maintain. Today, the Model A Ford engine is a popular engine among collectors and enthusiasts, and it continues to be a beloved piece of automotive history.
