The history of the internal combustion engine dates back to the late 19th century, when inventors like Karl Benz and Henry Ford revolutionized personal transportation. The advent of the mass-produced automobile led to an era of unprecedented mobility and shaped societal structures. The ICE operates by converting the energy stored in fuel into mechanical work, powering the vehicle's wheels through a series of controlled explosions within the engine's cylinders. This technology quickly became favored due to its ability to deliver high performance, convenience, and efficient range.

An engine thermostat is a temperature-controlled valve located in the cooling system of a vehicle. Its main function is to monitor the engine's temperature and regulate the flow of coolant to maintain an ideal operating temperature. Typically, an engine operates best at temperatures between 195°F and 220°F (90°C to 105°C). The thermostat opens and closes to allow coolant to circulate through the engine and the radiator, providing a delicate balance that prevents overheating or excessive cooling.

Oil-cooled engines utilize engine oil as a fluid to absorb and dissipate heat generated during combustion and friction processes. Unlike traditional air-cooled engines that rely on the flow of air and, in some cases, water, oil-cooled systems offer a more efficient means of temperature regulation. The oil not only serves as a lubricant for moving parts, reducing friction and wear, but also acts as a coolant, ensuring that the engine operates within optimal temperature ranges.

In terms of specifications, the engine stands out with its 4.000-inch bore and 3.622-inch stroke, allowing for a smooth and efficient combustion process. The dual-overhead cam (DOHC) design is engineered for enhanced airflow, which increases overall performance. Coupled with electronic fuel injection (EFI), the LQ9 is capable of delivering responsive driving dynamics and fuel efficiency, particularly in applications where power is paramount.
