China successfully completed an ignition test for its liquid-propellant engine with the highest thrust. This marks a new breakthrough in the country's liquid propulsion development. It is also the first-ever parallel ignition test of four large-thrust liquid oxygen (LOX) kerosene engines. 

The 130-tonne class LOX kerosene engine has a total thrust of over 500 tonnes. Compared to the currently operational 120-tonne class LOX kerosene engines, it boasts not only a larger thrust and better performance, but also a more compact structure, effectively enhancing the rocket's carrying capacity. After the test run, the engines will be delivered for rocket launching missions upon an engine check.
