Lin Tiejian: It is too early to predict when the diesel engine will disappear. Cost and scenario are the underlying logic of power selection.
November 15, 2022
November eleventh，The 21st China International Internal Combustion Engine and Power Equipment Exposition was held in Changsha。At the meeting，Yuchai appeared with a number of best-selling products。Lin Tiejian, Chief Engineer of Yuchai and President of Engineering Research Institute，The traditional energy of Yuchai is described in detail.、Dual layout strategy of new energy，And said：“Diesel engine and new energy are not sharp opposites.，Technically，The two should complement each other.。” Which power form is better?？User cost is the primary criterion
November tenth，The European Commission formally submits the Euro VII proposal.，The seven national standards are the same.“The rain is coming.”。Will increasingly stringent emission standards continue to compress the traditional diesel power market?？“Euro 7 is a huge step forward.，But for the entire diesel industry,，It is only one aspect.。Standards sometimes lead to innovation.。For example，Before the comprehensive upgrade of China VI Vehicle emission standards，Platform foundation of Yuchai、Product layout、Technological capabilities are already responding to higher industry standards.。Including fuel consumption index and electrification system、Integration of electrification components，This actually increases the range of Yuchai.、The exploration of diversified power forms such as hybrid provides a very good foundation.。Look at it from this angle.，The whole engine and new energy are actually closely integrated.。”Lin Tiejian first expressed his unique understanding of the standard.。
“In the short and medium term，We pay more attention to whether power products can bring value to users.。The standard is a boundary.，This is what Yuchai must do.。But from the perspective of the user of the terminal，The choice of power form depends on whether the product can bring value-added and benefits.。Whether it's a diesel、Hybrid、Fuel cell or pure electricity?，Or a multi-fuel form of internal combustion engine，I think the main criterion is whether it can cover the cost of users.。If it's only technically possible，However, it brings high cost to users.，The generalization of this dynamical system is open to question.。”On how to measure the form of power，Lin Tiejian also gave his own views.。Lin Tiejian concluded and emphasized：“From the perspective of user cost，Yuchai's product strategic layout has been considering how to realize the combination of traditional and new energy industries.，Provide the most appropriate solution for each market user。”
Which form of power has the most future?？
Scene is the first element
The choice of power form should first consider the needs of user cost.。Lin Tiejian also pointed out，The decisive factor of the future development of the power form depends on the scene conditions.。“I think it's time to predict when diesels will disappear.，It's too early.。Indeed, in some scenes,，Like a short trip or a port.，Pure electricity（Change the electricity）The proportion of products is increasing.，This also shows that this product is relatively more suitable for this scenario.。Many market segments of the current commercial Vehicle industry、Scenario conditions，It is hard to say which form of power is absolutely appropriate.。From the perspective of future development，The most appropriate dynamical form matches the most appropriate scenario is the underlying logic.。At present, many subdivision scenarios still need all-weather continuous input and output.，This is an irreplaceable advantage of diesel engines in the short term.。
From this point of view.，I think the diesel engine still has a long way to go.。”Lin Tiejian first pointed out the significance of scene decision.。He also further explained from the perspective of fuel diversification.：“From the perspective of fuel diversification，Wider application scenarios for internal combustion engines。Fuel cells, for example, are now considered the ultimate solution for long-distance logistics.，But it still has a long way to go in terms of cost and reliability.，It is possible that the hydrogen internal combustion engine will be a suitable transitional solution.。For this reason, the whole industry is also making full technical reserves.。Final，The foothold of scenario definition is to exert the maximum effect of the dynamic system itself.。”Which power form is Yuchai's choice?？Based on the above view，Lin Tiejian also elaborated on the strategy of Yuchai Power Program.：“On the whole，We must insist on the diversification of power.、Diversification of fuels，In essence, it is to achieve full coverage of traditional and new energy power.。Excavate the maximum benefit of the engine in the fusion，Implementation 1+1＞2。”
