The driver releases the accelerator pedal and keeps the clutch engaged. The forward kinetic energy of the truck reacts to the drive system and the engine to continue operation. The piston continues to reciprocate. The four strokes of intake, compression, expansion, and exhaust continue to cycle. Once the engine exhaust valve is started, the engine exhaust valve will be opened by the high exhaust back pressure, and the compressed high-pressure air will be discharged through the exhaust system, thereby reducing the work done by the high pressure air on the piston during the expansion stroke. Make the engine from the power output device into a power-consuming device (like an air compressor), consume the entire vehicle kinetic energy, in order to achieve the purpose of controlling or reducing the speed.
Polyvinyl Chloride or PVC Resin SG3, SG5, SG7 and SG8 are homopolymers made by suspension polymerization. PVC resin is white powder form thermoplastic resin and has great versatility for making plastic products.
SG3 is for films, hoses, leathers, wire cables and other general purpose soft products.
SG5 is for pipes, fittings, panels, calendaring, injection, moulding, profiles, and sandals.
SG7 / SG8 is for bottles, sheets, calendaring, rigid injection and moulding pipes.
