GM's new engine technology inventory, these new gadgets make everyone know American cars again

1. Variable cylinder technology Technology has been used by many manufacturers in recent years as a technology to reduce cruising emissions. GM has developed Tripower variable valve management technology for the four-cylinder models of the eighth-generation Ecotec engine series through DFM dynamic fuel management technology.

2. The new engine will be equipped with many main models under SAIC General Motors. In terms of displacement, it is not surprising that Chevrolet and Buick brands will be more common.

3. General engine: fourth generationNew product Ecol8504 engine The EcotecL8504 engine carried by Junyue is the fourth-generation brand-new product of the Ecotec series, which is the first engine in the family to apply VVT variable valve timing technology. It brings together GM's excellent global technical resources and integrates the technical essence of European and American engines.

4. The TLLU engine adopts an electronic thermostat and manifold injection, and the use performance is relatively stable. The maintenance rate is higher: the thermostat and water pump. Some engine piston rings are stuck and damaged, resulting in unstable engine operation. The overall performance is still good.

5. Therefore, don't look at domestic American cars and local American cars one-sidedly, and don't even use our concepts to understand the demand of the American automobile market. Many people mentionAs for the engine, I feel that the technology of Japan and Germany is very good, but I always feel that the American series does not seem to be as good at research and development and manufacturing as Japan and Germany.

6. As a new generation of Ecotec three-cylinder engine, SAIC General Motors will make a major change in the power system of its entry-level compact cars in the future. The 0T engine will gradually replace the 5L naturally aspirated engine, and the 3T will also gradually replace the original 4T.

What are the new technologies for automobiles

Flying cars The flying car called GOVE developed by GAC Group adopts a separate design. The simple understanding is that the aircraft and chassis can be separated, combined when driving on land, and the wings contract; empty It is separated during mid-flight, and the chassis is moored in the designated parking space.

New technology of automobilesThe technology includes: electronic monitoring braking technology, four-wheel drive system, chassis lifting system, 360-degree vision system, anti-skid system, etc. Electronic monitoring braking technology: This technology can shorten the braking distance by 50%.

Electronic monitoring and braking technology. Adopting this technology can shorten the braking distance by 50%. This intelligent braking device can obtain information at the moment of the driver's emergency braking, assist in manually increasing the braking force, and even when the driver releases the brake pedal due to panic, the device can continue braking. Anti-skid system.

What are the new technologies and structures of automobile engines? Briefly describe their structural principles, technical advantages and scope of application...

In-cylinder direct injection is one of the technologies relied on by many turbocharged engines at present. As the name implies, in-cylinder direct injection is to move the fuel injector previously located in the intake manifold to the cylinder. The advantage of this is to accurately control the air-fuel ratio and make the combustion more adequate.

New technologies used in automobile engines: VTEC technology, variable intake manifold technology, VVT-i technology, bias crankshaft technology, electronic throttle valve, CVVT (continuous variable valve timing system), FSI (in-cylinder direct injection layered combustion engine), MDS: (variable exhaust Measure the engine).

Characteristics and applications of new technologies for the main structure of automobiles: (1) Storage batteries, storage batteries are one of the two power supply equipment on automobiles and are the heart of automobile electrical systems. When the engine is running, the storage batteries supply the electricity required for electrical equipment;When the engine is running, the main uses are start-up power supply, low-speed power supply, and overload power supply.

The engine is composed of two major mechanisms: crank connecting rod mechanism and gas distribution mechanism, as well as five major systems such as cooling, lubrication, ignition, fuel supply and start-up system. The main components include cylinder block, cylinder head, piston, piston pin, connecting rod, crankshaft, flywheel, etc. The working cavity of the resurrected plug internal combustion engine is called a cylinder, and the inner surface of the cylinder is cylindrical.

The new technology used in automobile engines VTEC technology VTEC is an advanced engine technology developed by Honda, and it is also the world's first valve control system that can control the valve opening and closing time and lift in two different situations at the same time.
