What technology is used in the Geely Binrui 1.4T engine?

[StCamille]

Geely Binrui 1.4T engine uses multi-point fuel injection technology. Multi-point fuel injection: Multi-point fuel injection involves directly injecting fuel into the intake manifold of each cylinder, which then enters the corresponding combustion chamber. Each cylinder is equipped with an electromagnetic injector, allowing gasoline to be injected into the cylinder from multiple points. The invention of multi-point fuel injection fundamentally addresses issues such as uneven air distribution, reduced power, and increased fuel consumption caused by overlapping intake in adjacent cylinders, making it more advantageous in terms of emissions. Turbocharger: A turbocharger is an air compressor that primarily works by compressing air to increase intake volume. It utilizes the inertial force of exhaust gases expelled by the engine to drive a turbine in the turbo chamber, which in turn drives a coaxial impeller. The impeller then compresses air delivered through the air filter pipeline, pressurizing it before it enters the cylinder, thus forming the turbocharger system.

I've studied the 1.4T engine in the Geely Binrui, which is Geely's self-developed JLB-4G14TB model. At its core is turbocharging technology, paired with a small-inertia turbo design that kicks in at just 1500 rpm, delivering exceptionally responsive driving without lag. It also features a DVVT dual variable valve timing system that intelligently adjusts both intake and exhaust, striking a good balance between power and fuel efficiency. Particularly noteworthy is its low-friction design, with optimized piston rings and bearing shells, combined with an intelligent thermal management system for quick warm-up during cold starts - no more long waits in winter. Although it uses multi-point electronic fuel injection rather than direct injection, it excels in reliability and offers lower long-term maintenance costs. For a 100,000-yuan class sedan, this combination is quite competitive, providing ample power for daily driving while remaining fuel-efficient.

As an actual owner, I've been driving my Binrui 1.4T for three years, and this engine truly delivers. The most noticeable feature is the early turbo engagement, providing a strong push-back sensation even at low RPMs—it never disappoints at traffic light starts. Technically, it uses an all-aluminum cylinder block, significantly lighter than cast iron, enhancing overall vehicle agility. The dual VVT technology ensures excellent fuel efficiency; with AC on in city driving, it consumes just over 7L/100km. The plastic intake manifold in the engine bay isn't cost-cutting but a genuine lightweight design, with even hydraulic mounts considered for vibration control. Although it employs multi-point port fuel injection rather than direct injection, carbon buildup is minimal—mechanics say it's more reliable than direct-injection engines. On highways, the thermal management system shines, keeping coolant temperatures consistently stable.

After reading the disassembly report of the Binrui 1.4T, its most impressive feature is the balance shaft design. The dual counter-rotating balance shafts effectively suppress the vibrations of the four-cylinder engine, making the steering wheel almost vibration-free. In terms of technical details: the turbine blade diameter is only 40mm, and the wastegate is integrated into the turbo housing, resulting in a much lower failure rate compared to external setups. The valvetrain uses roller rocker arms, reducing friction by 40% compared to traditional slider types, making the cold-start ticking noise nearly inaudible. The hollow sodium-filled exhaust valves can lower temperatures by about 100°C, slowing down oil degradation. Although it doesn’t use high-pressure direct injection, the manifold injection pressure reaches 4bar, providing fully adequate atomization. The entire system puts significant effort into NVH and durability.
