in my opinion China product is best for these topic because these products are such products which is easily auto exhaust free from air pollution and charged with solar energy or batteries. China vehicles is good useful and auto exhaust free from air pollution.

Internal combustion engines operate by burning fossil fuels and produce a lot of exhaust emissions. They lead to a widespread odour and noise pollution. They also contribute to a lot of greenhouse gases such as carbon dioxide, methane etc. 

In order to reduce the pollution, a number of modifications could be carried out. These include. Turbo charging engines - smaller more efficient engines that produce the same level of power, advanced heat management and cooling systems to maintain the temperatures of the radiators. 

High strength steel - this helps in the weight reduction of the cars making it better and pollution resistant. 

Hybrid engines - that have an electric motor control.

low rolling resistance tyres - that are much flatter than the original tyres and help reduce friction. 

Value trimming of engines - these help in improving the fuel consumption of the engines. Lesser fuel used leads to lesser pollution.

Positive crankcase ventilation - these allow the vapours emitted during combustion to be burned in the air/fuel intake system. 

Particulate filters - these could be used to control the flow of pollutants emitted into the air.
