Phoenix engine is the Peugeot 1.6L engine with model number TU5JP4. Advantages of Phoenix engine: The advantage of TU5JP4 engine lies in its power output at high RPM. Without applying any advanced auxiliary technology, this engine can achieve a maximum power of 78kw/5750rpm and maximum torque of 142nm/4000rpm. Introduction to engines: Automotive engine is the power-generating device for vehicles, serving as the heart of a car that determines its power performance, fuel economy, stability and environmental friendliness. According to different power sources, automotive engines can be divided into diesel engines, gasoline engines, electric vehicle motors and hybrid power systems, etc. Engine working principle: A four-stroke gasoline engine mixes air and gasoline in a certain proportion to form a good combustible mixture, which is drawn into the cylinder during the intake stroke. The compressed mixture ignites and burns to generate thermal energy, and the high-temperature high-pressure gas acts on the piston top to push the piston for reciprocating linear motion, outputting mechanical energy through the connecting rod and crankshaft flywheel mechanism. A four-stroke gasoline engine completes one working cycle through intake stroke, compression stroke, power stroke and exhaust stroke.

I remember old drivers used to call it the 'Phoenix', referring to the Bosch fuel injection system paired with the 1.6L TU5JP4 engine used by Dongfeng Citroën in the early days. Back in the 1990s when carbureted cars dominated the streets, the sudden appearance of this fuel injection system in the Fukang was truly stunning. The engine cover bore the Phoenix logo, and its startup sound was remarkably crisp, with low fuel consumption and steady power. In those days, fuel efficiency was the real deal. Even now, when you occasionally spot an old Fukang on the road with hundreds of thousands of kilometers on the odometer, many have survived thanks to this system.

You're asking about that Citroën with the winged logo, right? Used to see it every day at the repair shop. The most amazing thing about this 1.6L engine is its incredibly smart fuel injection system – back in the 90s it could automatically adjust fuel delivery based on throttle position. But honestly, its catalytic converter was always clogging up; I've dismantled many exhaust pipes caked with thick carbon deposits. Yet the engine block itself is practically indestructible – I've seen taxi drivers rack up 700,000 km without major overhauls, and the crankcase still had a metallic sheen when opened.

Back in the day, auto repair magazines hyped this Phoenix system like crazy, but anyone who actually drove it knew how razor-sharp its response was. A light tap on the accelerator and it'd leap forward, cold starts in winter fired up at first crank. The most legendary was the modified 1998 Fukang rally champion – that engine ran flawlessly through the entire race. Later, the Peugeot 307 used the same system, just with upgraded ECU programming. Occasionally in the used car market, you'll spot an old 307 with that fiery phoenix emblem still visible under the hood.
