The Mercedes-Benz R107 450SLC 450SL 4.5L M117 engine is a masterpiece of automotive engineering, showcasing Mercedes-Benz's unwavering commitment to power, performance, and sophistication. This engine is a straight-six, SOHC design with an aluminum alloy block and cylinder head, and it displaces 4.5 liters or 273.6 cubic inches.

The M117 engine is known for its smooth and powerful delivery, producing 227 horsepower at 5,700 rpm and 273 lb-ft of torque at 4,000 rpm. It features Bosch Motronic fuel injection for optimal combustion efficiency and emission control. The engine is mated to a 4-speed automatic transmission or a 5-speed automatic transmission, depending on the year and specific model.

The six cylinders are arranged in a V configuration, with a 90-degree angle between each cylinder bank. The engine has a compression ratio of 9.3:1, which contributes to its impressive power output. The engine's valvetrain consists of a single overhead camshaft per cylinder bank, operating through a distribution system that delivers power to the intake and exhaust valves.

The engine's cooling system is designed to maintain optimal operating temperatures, even during heavy use. It features a water pump, a radiator, and a thermostat, which work together to regulate engine temperature.

The M117 engine's crankshaft is a forged steel component, which provides strength and durability. The connecting rods are also made of forged steel, ensuring a rigid connection between the pistons and the crankshaft. The pistons are made of aluminum alloy, which reduces weight and improves engine efficiency.

The engine's oil system includes a pressure relief valve, an oil cooler, and an oil filter. The oil system ensures that the engine is lubricated properly, reducing wear and tear and increasing the engine's lifespan.

The M117 engine's exhaust system features a catalytic converter and a muffler, which help reduce emissions and improve engine performance. The exhaust system also includes an oxygen sensor, which monitors exhaust gas composition and adjusts fuel injection accordingly to maintain optimal engine efficiency.
