A few days ago, in the interpretation of the "Made in China 2025" planning series issued by the Ministry of Industry and Information Technology, it was clearly proposed to promote the independent development of diesel engine high-pressure common rail technology and promote the application of diesel engines in passenger vehicles. This undoubtedly indicates that the dieselization of passenger cars that have been shackled and suppressed for a long time and has been controversial in the industry is welcoming an unprecedented and valuable development opportunity.
China's current number of diesel passenger cars is the lowest in the world, only 0.5% to 0.8%, which is far from the 60% diesel passenger car in Europe. Over the years, many large cities in the country, led by Beijing, have restricted diesel passenger cars, macroeconomic policies and the bundle of local policies, so that diesel passenger cars have always been on the edge of “not hurting, not lovingâ€.
In fact, with the continuous improvement of diesel engine technology, diesel passenger cars have not only got rid of the negative image of the old "mottlefish", but also have no obvious gap with the gasoline engine in terms of noise vibration and particulate matter emissions. Energy saving and emission reduction are even better than gasoline engines. The data shows that the diesel engine of the same displacement and the same model is generally 20%~30% lower than that of the gasoline version. At the same time, due to the continuous improvement and upgrade of the technology, it can provide more power than the same displacement gasoline engine. In addition, the diesel engine has excellent performance in reducing carbon dioxide emissions.
Therefore, in today's increasingly environmentally-friendly and energy-saving pressures, the automotive industry is also a normal growth space for diesel passenger cars, which is a disorder for diesel passenger cars.
In the face of the average fuel consumption of domestic passenger car manufacturers at the end of this year, the fuel consumption is 6.9L per 100 kilometers, and the fuel consumption limit of the fourth phase is stipulated that the average fuel consumption per 100 kilometers will be reduced to 5L by 2020. Most of the car companies feel "pressure mountain" ". In the 2014 average fuel consumption of passenger car companies announced by the Ministry of Industry and Information Technology, 38 car companies have not yet reached the standard. Therefore, in addition to gasoline engines and new energy technologies, it is imperative to further solve the problem of energy conservation and emission reduction through the diversification of vehicle energy. Diesel technology, which has been left out for many years, has the advantage of low fuel consumption, strong power and low emissions. It is finally expected to take this opportunity to receive attention and welcome rare development opportunities.
Is always shining gold. However, in the actual promotion process of diesel passenger cars, in order to truly achieve the goal of energy saving and emission reduction, it is still necessary to cooperate with relevant links. One of the keys is the improvement in diesel quality. Although "car oil matching" is a common topic, the phenomenon of unmatched fuel oil has long existed in the domestic passenger vehicle field. In the continuous upgrading and improvement of gasoline oil products, in order to match the emission standards of escalating gasoline vehicles, the goal of energy saving and emission reduction is truly achieved in the field of diesel passenger vehicles, and the quality of diesel oil is still important.
It is understood that since January 1 this year, the national standard diesel fuel has been supplied nationwide. By 2017, diesel oil products will be upgraded to the national five standard nationwide. This provides oil protection for the further promotion of passenger car diesel. It is hoped that with the Dongfeng of "Made in China 2025", passenger car dieselization will usher in great development and contribute to energy saving and emission reduction of motor vehicles.
