The next generation, opposed piston (“boxer”) internal combustion engine.
PROTOTYPE ENGINE SPECIFICATIONS
- air-cooled - 2 cylinder - 4 stroke - 8 valve - SOHC (single overhead cam) = straight shaft replaces the (regular type) crankshaft = disk + bearing ring replace the (regular type) connecting rod + piston pin - aligned and opposed cylinders - stroke = 60 mm - piston diameter = 85 mm - displaced volume = 680 cc = 0.68 liter (340 cc per cylinder)
LUBRICATION: - wet sump; external oil pump (Moroso; belt driven) - lubrication of main journals and disk bearing under hydrodynamic conditions - magneto ignition (Vertex) - cylinders and cylinder heads (Honda TRX 400) - overhead cam chain driven (Honda TRX 400 chain and sprockets) - main journal bearings (VW Type I standard (55 mm))
= performance data not yet available
Advantages: no connecting rods therefore slower volumetric expansion above the piston head during the first 90 degrees after TDC with fuel-air mixture explosion in a smaller- and slower expanding space than any engine with connecting rods resulting into a 24% or higher piston force in each cycle; no conrods, therefore fewer friction surfaces, and lower internal friction; no conrods, therefore no secondary forces and simpler engine balancing; in addition, simpler manufacturing/assembly.
The WAISSI engine can replace all internal combustion engines: aerospace (UAVs, light aircraft), automobiles, trucks, motorcycles, and can serve as an auxiliary power source.
The WAISSI ENGINE can be implemented as a 2-stroke and 4-stroke version using any fuel type.
3 US patents received, and one additional pending.

* The WAISSI ENGINE has the simplest possible opposed cylinder
opposed cylinder
An opposed-piston engine is a piston engine in which each cylinder has a piston at both ends, and no cylinder head. Petrol and diesel opposed-piston engines have been used mostly in large-scale applications such as ships, military tanks, and factories.

, opposed piston design. The design employs an integrated piston, driveshaft, crankdisk, and a bearing ring for each cylinder pair. There is not traditional crankshaft and no connecting rods.
There are two kinds of internal combustion engines currently in production: the spark ignition gasoline engine and the compression ignition diesel engine. Most of these are four-stroke cycle engines, meaning four piston strokes are needed to complete a cycle.
In the SI engine, fuel is mixed with air, broken up into a mist, and partially vaporized. The compression ratio varies from 4:1 to 8:1, and the air–fuel mixture ratio varies from 10:1 to 20:1. The four strokes of a petrol engine sucking fuel–air mixture are shown in Fig.
Allegedly, in 1860, several of these engines were built and used commercially in Paris. By 1867, about 280 units of the Lenoir engine had been built. Friedrich Sass considers the Lenoir engine to be the first functional internal combustion engine.

The simplest and most common type of engine comprises four vertical cylinders close together in a row. This is known as an in-line engine . Cars with capacities exceeding 2,000cc often have six cylinders in line.
The most common internal-combustion engine is the four-stroke, gasoline-powered, hom*ogeneous-charge, spark-ignition engine. This is because of its outstanding performance as a prime mover in the ground transportation industry.
Answer and Explanation: The most efficient combustion engine in the world is the Wärtsilä-Sulzer RT-flex96-C turbocharged 2-stroke Diesel engine that is used in over 300 large ships.
Higher Fuel Efficiency: CI engines are more fuel-efficient than SI engines, resulting in better mileage. Greater Torque: They produce higher torque at lower RPM, making them suitable for heavy-duty applications. Longer Engine Life: CI engines typically have a longer lifespan due to robust construction.
A spark-ignition engine (SI engine) is an internal combustion engine, generally a petrol engine, where the combustion process of the air-fuel mixture is ignited by a spark from a spark plug.
- SI engines natural gas will run at higher compression ratios, therefore manufacturing higher thermal efficiencies. - ethanol contains advantages of high-octane range and high combustion speed and has a disadvantage of adverse begin ability at vasoconstrictor.
A variety of SI engines are used in practice, depending on the application. Small SI engines are used in many applications: in the home (e.g., lawn mowers, chain saws), in portable power generation, as outboard motorboat engines, and in motorcycles. These are often single—cylinder engines producing a few kW of power.
The Wärtsilä-Sulzer RTA96-C turbocharged two-stroke diesel engine is the world's largest and most powerful production internal combustion engine. It has a maximum output of 84.42 MW (113,000 hp) of power and a displacement of 1,820 litres (110,195 cubic inches), making it larger than a V12 engine.
These experimental cars ran on steam, gasoline, or electricity. By the 1890s, Europeans were buying and driving cars made by Benz, Daimler, Panhard, and others, and Americans were buying and driving cars made by Duryea, Haynes, Winton, and others.
The Wärtsilä RT-flex96C is a two-stroke turbocharged low-speed diesel engine designed by the Finnish manufacturer Wärtsilä. It is currently considered the largest reciprocating engine in the world, designed for large container ships, running on heavy fuel oil.
The most common internal-combustion engine is the four-stroke, gasoline-powered, hom*ogeneous-charge, spark-ignition engine. This is because of its outstanding performance as a prime mover in the ground transportation industry.
noun. 1. : an engine (such as a steam engine) in which the expansion is completed in a single phase and exhausted to atmosphere or condenses after a single stroke of the piston compare compound engine.
INNengine is the first one to introduce 1 Stroke technology, meaning our engines have 2 power events per revolution in every cylinder. This allows them to deliver twice the power of a 2-Stroke and 4 times that of a 4-Stroke.
