Normal. Compression builds up quickly and evenly, to the specified compression for each cylinder. Piston Rings Leaking. Compression is low, on the first stroke. Consequently, compression builds up with the following strokes, but does not reach normal. And, your compression improves considerably, when you add oil. Valves Leaking
Wankel engines burn oil by design, hence not only it had bad emissions, but also poor fuel economy. The RX-8 was specifically engineered to curb this, but even then it still had an obviously inflated value of 22 MPG (more like, half of that when driven how it should), when a typical 1.3L of a normal piston engine were more than 3x as efficient.
Porqué no evolucionó el desarrollo del motor rotativo Wankel y su comparación con el motor de pistones. #AUTOTECNICATV te lo explica claro y simple con el In.

Introduction. The Wankel-type rotary engines are lightweight and have more compact designs, with fewer components, than conventional piston engines [1], [2].Since rotary motion can be obtained in Wankel Engines directly, there is no need to convert reciprocating motion into rotational motion as in reciprocating engines [3].Furthermore, Wankel engines can .A compression test is simple to learn and only requires a few basic tools. From a mechanical perspective, you will need to know how to properly remove the spark plugs on the vehicle or equipment you are testing and properly disable the ignition system and fuel system, the latter if the vehicle is fuel injected. For carbureted engines, you can choose to disable the fuel supply .
The design of the Wankel engine makes it far more powerful than a reciprocating engine of the same capacity. The NSU Wankel Spyder, with its 498cc engine giving a top speed of nearly 100mph, is one example. More recently, the Mazda RX-7 coupe has an engine capacity of only 1308cc (654cc per rotor), yet has similar performance capabilities to the Porsche 924S with a . Felix Wankel, a German engineer, came up with the Wankel engine in the 1950s.In a Wankel engine, fuel and air are compressed using a rotor that spins around a central driveshaft inside an oval .
Wet Compression Test Diagnosis. The results of a compression test can be quite telling. The results shown below indicate the particular area that needs attention. Worn piston rings/cylinder walls: After running the first test, squirt a teaspoon of oil into the cylinder and rotate the crankshaft six turns. If the compression increases, the .-These engines are not as effient as the Wankel engine in terms of the Otto Cycle. It takes to rotations of the crankshaft for the piston to have a power stroke in comparison to the Wankel engine having three power strokes per rotation Pros and Cons of the Wankel Rotory engine: Pros:-It has less parts and weighs less than the reciprocating engine
Gasoline octane requirements are higher than for piston engines, due to the high compression ratios required for rotary engines; Susceptible to “knocking” or “pinging” if not using premium gasoline. It has a lower fuel efficiency than a piston engine. It produces more emissions than a piston engine. It is less reliable than a piston engine. Wankel Engine Piston Engine; It has a rotary rotor which is used to convert the thermal energy into rotatory motion. . Wankel engine has a compression ratio from 9:1 to 11:1.
