Spring Starter (Spring energy storage starting) is a technology that only requires manpower to start the engine. This technology is suitable for engines in various emergency environments. Engine batteries in emergency environments often encounter long-term storage and lack of power, resulting in insufficient starting ability of the electric motor, which makes the entire engine system unable to operate, which is very dangerous in an emergency environment.
However, due to the limitation of the product’s technical capabilities, the spring energy storage start is used as an emergency start, which is very suitable for engines within 10L. Among the spring starters produced by manufacturers around the world, the spring is an energy-storage start, and the maximum starting capacity can only start an engine of about 13L.
Therefore, in the traditional market, the emergency engine above about 13L adopts the air start method. Because the air start requires the support of a complete air start system to work, and there are many matching parts, maintenance and maintenance are more difficult. Many customers Hope to have a spring energy storage start product for large displacement engines.
Cqstart has been committed to the research of spring starters supporting traditional small-displacement engines. However, with the increasing demand from customers for spring starters for large-displacement engines, CQ starters continue to study starting solutions for large-displacement engines.
Spring Starter for 20L Engine
This kind of spring starter is based on the existing spring energy storage starter, increasing the overall transmission mechanism as much as possible, increasing the volume of the energy storage device, thereby adding more springs. Due to the increase of the spring, the increase of the transmission and mechanism, the torque strength, etc. will be affected, so it is necessary to re-customize the structure and material of the spring starter. The volume and capacity of the final molded product have increased by nearly 30%. Equipped with Cummins K19 engine (19L displacement) for 30 start-up experiments with load, the start-up success rate is 100%, which perfectly meets the design requirements.
Spring Starter for 30L Engine
Because the design value of the torque strength of the transmission mechanism has reached the limit, it cannot be increased, but there are still large-displacement engines that require spring energy storage starters. Take a V-shaped 12-cylinder 29L engine as an example. The torque of the engine has reached its limit, so it is impossible to add more springs. In the end, Cqstart selected a variety of special materials, and after continuous research on the manufacturing process, finally developed a super spring. With the same lifetime, the energy density is 25% higher than the previous maximum capacity. And because of the better starting performance of the 12V model, the 29L engine started very successfully, setting a new record again.
Spring Starter for 50L Engine
Under the special design idea of the last spring energy storage starting system, Cqstart started to develop a spring starter for a larger displacement engine to start the Cummins K50 engine. Based on the previous synchronizer structure, many optimizations have been carried out. The inside of the product is plated with a layer of special precious metal. The product parts processed by this process have transmission efficiency and impact resistance. Ability is significantly improved. Shuanggao quickly prepared a test prototype and negotiated with the engine factory to test it on the Cummins K50 engine. After many energy storage start cycles, the spring energy storage start system can meet the engine’s starting requirements, breaking the world record of 50L displacement spring start.
So far, the spring starter is not only used as an emergency starter for small displacement engines but can realize emergency start for engines with displacements from 2L to 60L. Cqstart’s spring starter has been recognized by customers for its excellent performance.
