Let's talk about the Jiangling brand engine produced by Jiangling Machinery Factory under Changan Group. Changan bread and its engine are copied from Japan. Jiangling engine is as famous as Dongan engine. They are probably the earliest manufacturers of small displacement engines in China. At present, there are many brands of autonomous vehicles, such as JAC's 1.3 VVT and 1.5 VVT engines, all of which are Jiangling's, which is good.
How can I put it? It is certain to adopt Suzuki's technology, but it must be clear that it is made in China and all are Jiangling engines. Jiangling engine was originally imported from Japan, and later I bought the technology and production line of Isuzu in Japan. It is a real engine of Isuzu technology. There are only two engines using this technology in China, one is Qingling and the other is Jiangling.
Jiangling's engine (actually incorporated into Changan Automobile as early as 10 years ago) is the biggest highlight of the whole Changan series (except Changan Ford). Both Changan Automobile and Changan Suzuki use Jiangling engines. Generally, antelope taxis in Chongqing can run more than1100,000 kilometers without overhaul for four years, and their engines belong to the same series as Yuexiang's engines.
JL474Q
Engine structure type
In-line four-cylinder, 16 valve, single (double) overhead camshaft, four-stroke engine.
Computer-controlled multi-point closed-loop sequential gasoline injection, computer-controlled ignition system with knock detection.
Main characteristics of engine
The F and G series engine technologies of Japanese Suzuki Company are adopted, and advanced engine computer management systems such as Denso, UMC, Ma Ruili and Delphi are selected.
The engine has compact structure, reasonable layout, strong power, low oil consumption, low noise, high reliability and environmental protection.
It has been applied to Changan brand series mini-cars: Otto cars, Changan Star series vans, Nanjing Changan series mini-cars, Changan Shengli series mini-cars and so on.
It is an ideal engine for domestic mini-cars, buses (business, reconnaissance, postal services, ambulances, prisoners and passengers), trucks and vans.

The CX20 is equipped with 474QL series engines and the transmission with patented technology of 14. It adopts the latest Japanese technology, adopts all-aluminum lightweight materials as a whole, and has the maximum power of 63kw/rpm and the maximum displacement of1.3l. It has the characteristics of long life, high power, low vibration, low noise, low fuel consumption, low emission, light shifting and no impact noise. This has obvious advantages in competing cars equipped with 0.8- 1.2L engine, which not only ensures the driving force, but also greatly improves the driving pleasure. In addition, the engine has undergone a number of power matching tests, such as the strict start-up test at MINUS 34 degrees in winter, the use test at an altitude of more than 5,000 meters in summer, and the harsh 500-hour continuous full-load bench test. According to the comprehensive fuel consumption of major vehicles announced by the National Development and Reform Commission, the comprehensive fuel consumption of CX20 is 6.7L/ 100Km, and the economic fuel consumption is less than 4.3L (under the condition of 50 km/h constant speed driving).
