Inline engines are generally abbreviated as L. For example, L4 represents the meaning of an in-line 4-cylinder. The inline layout is the most widely used cylinder arrangement today, especially on engines with displacements up to 2.5L. All the cylinders of this type of engine are arranged side by side at the same angle into a single plane, and only one cylinder head is used. At the same time, the structure of its cylinder and crankshaft should be relatively simple, such as the cylinders standing in a column.
Inline engine
The so-called V-engine, simply put all the cylinders into two groups, the adjacent cylinders are arranged together with a certain angle, so that the two groups of cylinders form an angle plane, from the side view of the cylinder was V-shaped (usual angle For 60°), it is called a V-type engine. Compared with the in-line layout, the V-type engine shortens the length and height of the body, while the lower mounting position allows the designer to design a body with a lower drag coefficient, while benefiting from the arrangement of the cylinders, which can also offset part of the Vibration, making the engine run smoother.
　　 V type engine
Compared with the common L-type and V-type cylinder layouts, the rotary engine is different. It directly converts the combustion expansion of flammable gas into the driving torque. Compared with the reciprocating engine, the rotary engine eliminates useless linear motion. Therefore, the same power of the rotary engine is smaller in size, lighter in weight, and lower in vibration and noise, and has greater advantages.

Super-Soft PVC/Nitrile Sponge Rubber
A new semi-closed cell version has been developed as an alternative to Nitto and Armacell grades. The product is a standard PVC/Nitrile sponge rubber and the cells have been crushed to open some of them up to create a soft low compression seal product.
Properties:
- Density is approx. 90 Kg/m³
- Excellent Air & UV resistance
- Poor oil resistance
- Good Acid resistance
- Ultra soft with little compression required to deform it.
Typical Uses:
- Sealing of Air Conditioning Ducts
- Areas for superior water tightness
- Instrument panel mounting
- Windscreen mounting
- Mirror mounting
- Centre Pillar Mounts
- Seals where uneven surfaces are present
