The Renault K4M engine, a core power unit of the K-Type series, is a 1.6L inline-four naturally aspirated gasoline engine validated by over 20 years of market practice. With its mature and stable technical structure and wide adaptability, it has become a classic power choice for multiple brands including Renault, Nissan, Dacia, and Lada. This newly assembled version strictly adheres to Renault's original factory manufacturing standards and assembly specifications, adopting precision assembly processes throughout the entire workflow. All components meet original specifications, and every fit from the cylinder block to the valve train undergoes strict verification to ensure the continuation of its proven reliability and durability.

It boasts impressive core technical highlights: Equipped with a DOHC (Double Overhead Camshaft) design paired with a 16-valve structure, combined with a variable valve timing system and electronic fuel injection technology, it precisely controls fuel injection volume and valve timing to achieve efficient combustion. While delivering a maximum power of 102-115 horsepower and a peak torque of 145-155N·m, it balances excellent fuel economy (combined cycle fuel consumption as low as 8.4L/100km) and meets Euro IV to Euro V emission standards. The engine features a high-strength cast iron cylinder block combined with an aluminum alloy cylinder head, balancing structural rigidity and lightweight advantages. Equipped with lightweight camshafts, reinforced pistons, and hydraulic tappets, it not only operates smoothly with low vibration and noise but also achieves a practical service life of over 400,000 kilometers. It is compatible with various mainstream models such as Renault Megane, Scenic, Dacia Duster, Nissan Almera, and Lada Largus.

All engines undergo professional hot run-in tests before leaving the factory: first running at 800-1000r/min for 1 hour without load to fully inspect the sealing and operating status of the oil-electrical circuit, cooling system, and lubrication system; then conducting loaded run-in with 10%-15% rated load to optimize the adaptability of part friction surfaces and identify potential hazards. After run-in, key indicators such as cylinder pressure and piston run-in marks are verified to meet standards through disassembly inspection, ensuring the engine reaches the optimal working condition upon delivery and can be put into use without additional run-in.

We provide a one-year warranty for this newly assembled engine, covering assembly process defects and core component quality issues during the warranty period (excluding consumables and human-induced damage). With professional protection, it escorts daily commuting and commercial operations, allowing you to enjoy a stable and efficient power experience.
