The F3L912 is a three-cylinder, naturally aspirated engine with a displacement of 2.828 liters.
It operates on the four-stroke principle, which means it goes through intake, compression, combustion, and exhaust cycles. The engine's bore and stroke measure 100 mm and 120 mm, respectively, resulting in a relatively high torque output.
This engine utilizes a mechanical injection system, where fuel is injected into the combustion chamber at high pressure. This system ensures efficient fuel atomization and precise fuel delivery, resulting in optimal combustion and reduced fuel consumption. The fuel injection pump is driven by the engine's timing gears, providing accurate injection timing.
The cooling system of the F3L912 consists of a radiator, water pump, and thermostat. It relies on a liquid cooling mechanism, which helps maintain the engine's temperature within the desired operating range. The engine is equipped with an air-cooled oil cooler to regulate the oil temperature and ensure its proper lubrication.
In terms of lubrication, the F3L912 employs a pressure lubrication system with a gear-driven oil pump. This system ensures that all vital engine components receive a sufficient supply of oil, reducing friction and wear. A full-flow oil filter is incorporated to remove impurities and contaminants from the oil, ensuring its cleanliness and prolonging the engine's lifespan.
The F3L912 engine features an overhead valve (OHV) design, where the valves are positioned above the cylinder head. This configuration allows for better airflow and efficient combustion. The valves are actuated by a camshaft and are equipped with hydraulic valve lifters, which eliminate the need for periodic valve adjustments.
When it comes to electrical systems, the F3L912 can be equipped with either a 12-volt or 24-volt starter motor and alternator, depending on the application requirements.
The engine is designed to provide reliable cold starting capabilities and robust electrical power generation for auxiliary equipment.
The compact and lightweight design of the F3L912 makes it suitable for installations where space is limited. Its robust construction, coupled with the use of high-quality materials, ensures long-lasting performance even in demanding operating conditions. The engine is designed to meet various emission standards, including those set by the European Union and the U.S. Environmental Protection Agency (EPA).
