Abstract
The present disclosure relates to a camless engine in which a camless system is configured for controlling one or more engine valves of an internal combustion engine is disclosed. The system comprises a pneumatic accumulator configured to store compressed air, and at least one pneumatic actuator having a piston rod. The pneumatic actuator is configured for abutment with the engine valves of the internal combustion engine. The system further comprises at least one pneumatic control valve fluidly connected between the pneumatic accumulator and the pneumatic actuator, a sensor configured to sense an engine parameter and to transmit a signal to actuate the pneumatic control valves and an electronic control unit configured to control the pneumatic valves based on the signal received from the sensor.
Claims20
A pneumatic actuator for controlling one or more engine valves of an internal combustion engine, the pneumatic actuator comprising:
- an actuating chamber and a piston rod mounted slidingly inside the actuating chamber;
- at least one pneumatic control device operationally configured with the pneumatic actuator;
- at least one sensor configured to sense an engine parameter and to transmit a signal to the pneumatic control device;
- wherein the pneumatic actuator is configured to achieve the opening and closing of the engine valves for a predetermined period based on the signal received from the sensor corresponding to the engine parameters.
A camless system for controlling one or more engine valves of an internal combustion engine, the system comprising:
- a pneumatic accumulator configured to store compressed air;
- a plurality of pneumatic actuators configured for abutment with the engine valves of the internal combustion engine;
- at least one pneumatic control device fluidly connected between the pneumatic accumulator and the pneumatic actuator;
