Any one car brand, mostly familiar classic models, but these classic heritage are inseparable from its core technology blessing, because it is a car brand value and essence where today we have to talk more The core of the black car brand technology, bragging with high cold range children!
EARTHDREAM / i-MMD mixing system
EARTHDREAM, Honda engine technology system collectively, that is, the original Honda engine VTEC (variable valve timing and lift electronic control system) technology, joined the VTC (continuously variable valve timing), direct injection, Reduce a series of cylinder friction and other technologies to achieve the best balance between engine fuel economy and performance.
i-MMD hybrid system, Honda fuel blending technology Unlike Toyota's THS hybrid system, the Honda i-MMD hybrid system is a hybrid system that tends to be pure electric motor-driven vehicles, the engine is mainly responsible for the power supply to the motor , Battery charging, not directly involved in the wheel drive, and the maximum power of the motor carried to reach 158Kw, acceleration within 100 km within 8S, to achieve the same fuel economy and performance, then a box of oil run 2000km Accord, obviously not a gimmick It's
TFSI
TFSI, VW's stratified combustion technology, is a suite of new technologies based on a hybrid injection system designed to improve fuel efficiency.
TFSI technology will be based on precise control of engine fuel injection quantity, that is, under low load conditions, the intake manifold injectors in the intake stroke into the thin oil and gas mixture, coupled with the compression stroke when the cylinder direct injection Sprayed oil mist, ignition spark plug to achieve stratified combustion, to maximize combustion efficiency.
TFSI, also known as hybrid injection, EFI and direct injection technology with the role of combustion to achieve maximum work, and effectively reduce the direct injection engine easy to form valve and cylinder carbon. Currently, only the Audi models equipped with this technology.
VVT-i / THS hybrid system
The VVT-i, Toyota's variable valve timing technology, provides accurate control of engine speed, intake air amount, throttle position, and cooling water temperature by driving a computer by evaluating the current engine operating conditions to achieve maximum engine performance At the same time, each sensor will feedback the engine execution condition, compensate the system error, adjust the position of the camshaft to the optimal valve timing, and then effectively improve the car's power and performance and minimize the fuel consumption and exhaust emissions.
THS hybrid system, known as Toyota's famous fuel blending technology. THS hybrid system is a strong hybrid, the combination of Atkinson cycle motor + motor, low speed, the use of motor-driven vehicles, the dynamic response is more direct; When the engine intervenes, motor-assisted drive through the engine, the motor switching power linear, stable output, but also take into account the excellent fuel economy.At present, Toyota's latest second-generation THS hybrid system, the engine thermal efficiency reached The astonishing 42% is the highest thermal efficiency currently available in mass production engines.
DRIVE-E, Volvo's dual supercharger technology, namely supercharger + turbocharger, that is, when the engine turns low, the supercharger will intervene in the engine to make up for low-torque output of the engine without any power delay; Turns, turbo pressure has been established, the turbocharger will intervene in the engine work, the supercharger will stop working, and turbocharged will not unexpected intervention.
At present, Volvo uses the DRIVE-E series engine, modular design, all 2.0L displacement, of which T4, T5 is a high and low power turbocharged engine, T6 is a dual supercharged engine.
SKYACTIV, Mazda's Chi-Chi technology is not a single engine technology, but the general term for the automotive platform modular technology, including the chassis, body, engine, transmission and so on.
The SKYACTIV biggest bright spot is through the control of the timing system to achieve expansion ratio greater than the compression ratio, to achieve high combustion rate Miller cycle, while allowing the engine to achieve variable compression ratio, the maximum compression ratio of 14: 1, so that the engine always Work in the best economic conditions.
At the same time, Mazda's second-generation Skyrim engines will join HCCI and raise the maximum compression ratio to 18: 1, while the thermal efficiency will reach 50%.
