What is the fuel injection method of the New Baojun RC6 engine?

[VonGriffin]

The fuel injection method of the New Baojun RC6 engine is multi-point injection, also known as multi-valve injection or sequential fuel injection, as opposed to single-point injection. Each cylinder is equipped with an injector, and each injector separately injects fuel into the intake tract (in front of the intake pipe) of each cylinder, making it a relatively common injection system. The New Baojun RC6 is a mid-size car under SAIC-GM-Wuling, fully compliant with the China VI emission standards, with dimensions of 4925mm in length, 1880mm in width, and 1580mm in height, and a wheelbase of 2800mm. The New Baojun RC6 is equipped with a 1.5T version of the engine, paired with a 6-speed manual transmission and a CVT continuously variable transmission. The 1.6T version of the engine has a maximum output power of 108 kW and a maximum torque of 250 Nm. The exterior design of the car uses a new family-style design language, with a hexagonal grille featuring a starry sky design and a new diamond emblem.

As a tech enthusiast who frequently studies engines, the 1.5T turbocharged engine in the Baojun RC6 uses direct fuel injection technology. Simply put, the fuel injector sprays fuel directly into the cylinder, unlike older port fuel injection systems that spray fuel into the intake manifold. This design allows for better mixing of gasoline and air, resulting in higher combustion efficiency, stronger power output, and relatively better fuel economy. However, direct injection tends to cause carbon buildup on the back of the valves, so it's recommended to use fuel additives regularly or take highway drives to mitigate this. The RC6 is tuned for smoothness, and it pairs well with direct injection—turbo lag is hardly noticeable in city driving.

I've been driving the RC6 for almost two years now, and I specifically checked the manual - its 1.5T engine is indeed direct injection. The advantage is particularly crisp acceleration from standstill, especially when overtaking, the throttle response is very precise. During my last maintenance, the technician mentioned that direct injection engines require attention to fuel quality. While 92-octane fuel can be used, it's recommended to use 95-octane for better cleanliness, which provides better protection for the fuel injectors. Carbon buildup is indeed an issue, but I add a bottle of the manufacturer's fuel system cleaner every 5,000 kilometers, and so far haven't experienced any idle vibration issues.

From a technological iteration perspective, the RC6 direct injection system qualifies as mainstream configuration. It utilizes a high-pressure fuel pump to atomize gasoline more finely, achieving injection pressures around 200 bar, with injection timing precisely coordinated with intake swirl. Compared to older Baojun's port fuel injection, it reduces cold-start emissions and warms up faster in winter. However, the higher cost necessitates more meticulous maintenance, particularly regular inspections of high-pressure fuel circuit sealing to prevent undetected leaks.

For regular car owners in daily use, there's no need to delve deeply into direct injection principles. Just remember two key points: First, don't cheap out on gas by going to small, unreliable stations - clogged fuel injectors are expensive to repair. Second, during maintenance, ask the mechanic to thoroughly inspect spark plugs and ignition coils, as direct injection engines operate at higher temperatures, causing these components to wear out faster. My RC6 recently experienced misfiring due to worn spark plugs, costing over 800 yuan for a full replacement set.

Compared to other models in the same price range, the RC6's direct injection system is tuned for fuel efficiency. Its fuel injection strategy actively coordinates with the CVT transmission, such as reducing injection pulse frequency during steady-speed cruising. However, it can instantly increase fuel injection volume during aggressive driving—the official claim of 0-100km/h acceleration in just over 9 seconds relies on this feature. The characteristic 'clicking' sound of direct injection engines can be heard in quiet environments, which is normal and nothing to worry about. If the noise bothers you, switching to a slightly higher viscosity engine oil can help reduce it.
