How does Big Dipper distinguish domestic and Japanese engines?

The engine of Suzuki Big Dipper is not made in China, but in Japan.

Suzuki Big Dipper is a small engine-K14B engine of Suzuki Corporation of Japan, which adopts all-aluminum components, 4-cylinder 16 valve DOHC technology and thin-walled cylinder design.

Engine K 14B has a maximum output of 67Kw/6000rpm and a maximum torque of 1 12(N? M)/4,000 rpm. Driving at a constant speed of 50 kilometers, the fuel consumption per 100 kilometers is 4 liters, and the 5-speed manual transmission of the Big Dipper 1 and the second gear accelerate normally. When the speed reaches 40 kilometers per hour, the driving distance is about 5 meters, and the acceleration time of 0- 100 kilometers is 16.30 seconds.

Working principle of Suzuki Big Dipper extended information engine;

A machine that converts chemical energy into mechanical energy, the conversion process is actually the process of working cycle. To put it simply, the fuel in the combustion cylinder generates kinetic energy, which drives the piston in the engine cylinder to reciprocate, thus driving the connecting rod connected with the piston and the crank connected with the connecting rod to reciprocate around the center of the crankshaft and output power.

The piston is driven by the crankshaft and moves from top dead center to bottom dead center. At the same time, the intake valve opens and the exhaust valve closes. When the piston moves from the top dead center to the bottom dead center, the volume above the piston increases and the gas pressure in the cylinder decreases, forming a certain degree of vacuum. When the intake valve is opened, the cylinder communicates with the intake pipe, and the mixed gas is sucked into the cylinder. When the piston moves to the bottom dead center, the cylinder is filled with fresh mixed gas and exhaust gas not discharged in the last working cycle.

At the end of the exhaust stroke, the piston returns to the top dead center. It also completed a work cycle. Subsequently, the crankshaft continues to rotate through the inertia of the flywheel rotation and starts the next cycle. In this way, the engine keeps running.
