• In Internal combustion engines in order to increase the thermal efficiency of the engine and reduce emissions, several strategies are carried out such that homogeneous mixture preparation  can be achieved through direct early injection and external injection techniques in the intake manifold.
• But to provide a controllable heating, the systems available currently are not effective enough to achieve higher degree of homogeneity with low volatile fuels.

• A high pressure fuel injection system for use in an internal combustion engine comprising of:
• An anti chamber
• A ceramic heater mounted on the outer periphery of the said anti chamber that heat anti-chamber
• A fuel injector positioned at the centre of the anti-chamber to ensure uniform fuel distribution along the inner periphery of the heated anti chamber
• an air inlet to the anti-chamber; and a control system for controlling the amount of fuel through the solenoid injector,
• Further, the high pressure fuel injection is timed to occur during the suction stroke of the engine so as to deliver the well mixed lean homogeneous fuel-air mixture into the engine combustion chamber.

Further discloses  a method comprising the steps of :

• Heating an anti-chamber by a ceramic heater and positioning a fuel injector at the centre of the anti- chamber for ensuring uniform fuel distribution
• Inletting air inlet to the anti-chamber
• Controlling the amount of fuel through the solenoid injector
• Delivering the well mixed lean homogeneous fuel-air mixture into the engine combustion chamber.
