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.

The most practical aspect of this car's engine is its maintenance convenience. Its timing chain is maintenance-free for life, unlike belt-driven engines that require periodic replacement. The oil filter is designed as a top-mounted type, allowing easy replacement during maintenance without needing a lift. The turbocharger utilizes Mitsubishi Heavy Industries technology, with a water-cooled intercooler integrated into the intake manifold, offering 30% higher cooling efficiency than air-cooled systems. I've personally disassembled the throttle body and found an anti-carbon deposit coating in the intake tract, eliminating the need for cleaning until 30,000 kilometers. Using 5W-30 full synthetic oil is sufficient, unlike some turbocharged cars that require premium-grade oil. The alternator bracket features vibration-damping rubber pads, preventing resonance noises even under high electrical load. While the technology isn't flashy, it's exceptionally practical.

Young people choose the Binrui 1.4T for its balanced technology. The all-aluminum cylinder block reduces weight by 15 kg, making acceleration noticeably quicker. The combination of dual VVT and a low-inertia turbocharger delivers 235 Nm of torque at just 1800 rpm, making it easy to outperform a Civic. The cylinder head integrates the exhaust manifold, allowing the coolant temperature to reach 90°C in just two minutes during winter, providing fast warm air without wasting fuel. A polymer oil pan is specifically used, so there's no worry about oil leaks even if hit by stones. The most surprising part is the smart ECU calibration—it downshifts decisively when the throttle is floored, and never lags during uphill climbs in mountainous areas. Although the maximum horsepower is only 141 hp, the wide torque plateau ensures a strong push-back sensation even during 80-120 km/h acceleration.
