What are the disadvantages of hybrid injection?
2 Answers
Engines equipped with hybrid injection do not match the fuel efficiency of direct injection engines. Related information: 1. Reason: Hybrid injection combines both direct injection and multi-point fuel injection. Hybrid injection engines can use different injection methods under different working conditions, which means the fuel efficiency of such engines cannot match that of direct injection engines. 2. Introduction: An engine (Engine) is a machine that can convert other forms of energy into mechanical energy, including internal combustion engines (reciprocating piston engines), external combustion engines (Stirling engines, steam engines, etc.), jet engines, electric motors, etc. The term engine can refer to both the power generation device and the entire machine including the power unit (e.g., gasoline engines, aircraft engines).
The concept of dual injection (port and direct) sounds advanced, but personally, I believe its biggest issue is being a money pit. The system design is overly complex, incorporating both direct injection and port injection setups, which multiplies the number of components. Parts like injectors and control modules are prone to frequent failures. I’ve driven such a car for nearly three years, and the maintenance costs are exorbitantly high. Most regular repair shops can’t handle it, forcing you to visit 4S dealerships or specialized service centers. Last year, an injector failure cost me over 2,000 RMB in replacement parts and several days without the car. The initial purchase price is also steeper—about 10,000 RMB more than traditional injection systems—which is a significant burden for budget-conscious buyers. While fuel efficiency is slightly better, long-term calculations show that the savings on fuel don’t offset the repair bills. Additionally, in colder regions, the system is more prone to issues, requiring extra heating protection and higher maintenance frequency. My advice to average consumers: think twice before buying. Don’t just focus on the fuel-saving benefits—the actual expenses might leave you regretting the decision.
