With the advancements in Engineering, we have been witnessing some drastic leaps and slopes on every edge of the possibilities and been making efforts to get the best out of everything. Various ideas have been brought out to seek the most efficient outcomes in all the sectors. Among those, IC Engines have been one of the greatest inventions by humankind. Many developments are made in them and one such thing is the Opposite piston engines. They have many architectural advantages like good balancing, high thermal efficiency, less fuel consumption, high power density, torque etc., this type of engine ceases itsexistence today mainly because its emission issues and its complexity. We used the concept of this opposite piston engine to develop a novel cross cylinder four piston synchronous engine which will be more efficient than the conventional engine. This engine will have all four pistons acting simultaneously producing four power strokes at the same time to achieve maximum torque with less balancing issues. Also our concept is to provide inlet and exhaust ports on either side of the cylinder. This allows the reduction of port opening and closing time and thus improvising, making it suitable for any kind of cylinder configuration for their efficient usage. Various parameters of this engine such as torque, rpm, efficiency etc., is validated through the fabricated model, manual calculation and by simulation.
