Cylinder Head, Yamaha r6 engine diagram

The cylinder head is the brain of the engine, housing the valves, camshafts, and spark plugs. Its primary role is to control the flow of air and fuel into the cylinders and exhaust gases out of them.

Pistons and Connecting Rods

Pistons are cylindrical components that move up and down within the cylinders. They receive the force from the combustion process and transfer it to the crankshaft via connecting rods.

Yamaha R6’s engine is an inline-four cylinder, liquid-cooled, four-stroke engine that produces 118.4 horsepower and 52.4 lb-ft of torque. The engine is paired with a six-speed transmission.

The Yamaha R6 engine diagram shows the detailed layout of the engine, including the location of the cylinders, pistons, crankshaft, and other components.

Camshaft and Timing Chain

The camshaft is a crucial component that controls the timing of the valves. It opens and closes the valves at precise moments to ensure optimal engine performance. The timing chain connects the camshaft to the crankshaft, synchronizing their movements.

Oil Pump and Lubrication System

The oil pump ensures that all moving parts of the engine are adequately lubricated. It circulates oil throughout the engine, reducing friction and wear, and maintaining optimal engine health.

Intake and Exhaust Systems

The Yamaha R6’s intake and exhaust systems play a crucial role in optimizing engine performance. These systems are meticulously designed to ensure efficient air-fuel mixture delivery and effective exhaust gas removal.

The intake system consists of a fuel injection system and throttle bodies. The fuel injection system precisely delivers fuel into the engine’s cylinders, ensuring an optimal air-fuel ratio for combustion. The throttle bodies control the airflow into the engine, adjusting the mixture based on the rider’s throttle input.

Exhaust System

The exhaust system comprises headers, a catalytic converter, and a muffler. The headers collect exhaust gases from the cylinders and direct them into the catalytic converter. The catalytic converter reduces harmful emissions by converting pollutants into less harmful substances. The muffler dampens the exhaust noise, ensuring compliance with noise regulations.

Engine Management System

The engine management system (EMS) is the brain of the Yamaha R6 engine, controlling various aspects of its performance to optimize power, efficiency, and emissions. It consists of a series of sensors, actuators, and a computer that analyzes data and adjusts engine parameters accordingly.

If you’re keen on learning more about the intricate details of the Yamaha R6 engine, studying its diagram is a great place to start. For those curious about the engine’s cubic capacity, you can find comprehensive information on the Yamaha R6 cc . Returning to the engine diagram, it provides a visual representation of the engine’s components and their interconnections, helping you understand its inner workings.


The EMS relies on a network of sensors to monitor engine conditions. These sensors include:

  • Throttle position sensor (TPS): Measures the position of the throttle valve.
  • Intake air temperature sensor (IAT): Measures the temperature of the air entering the engine.
  • Coolant temperature sensor (CTS): Measures the temperature of the engine coolant.
  • Oxygen sensor (O2 sensor): Measures the amount of oxygen in the exhaust gases.


The EMS uses actuators to adjust engine parameters based on sensor data. These actuators include:

  • Fuel injectors: Control the amount of fuel injected into the engine.
  • Ignition coils: Control the timing and intensity of the spark plugs.
  • Variable valve timing (VVT) system: Adjusts the timing of the intake and exhaust valves.

Engine Maps

The EMS stores a series of engine maps that define how the engine should behave under different operating conditions. These maps include:

  • Fuel map: Controls the amount of fuel injected at different engine speeds and loads.
  • Ignition map: Controls the timing and intensity of the spark plugs at different engine speeds and loads.
  • VVT map: Controls the timing of the intake and exhaust valves at different engine speeds and loads.

By adjusting these maps, the EMS can optimize engine performance for different riding conditions, such as acceleration, cruising, and fuel economy.
