Is the new Alto a timing chain or a timing belt?

Compared with traditional belt drive, chain drive has the advantages of reliable transmission, good durability and space saving. The system consists of gears, chains and tensioners, and its hydraulic tensioner can automatically adjust the tension, so that the chain tension is consistent and maintenance-free for life. Super durability makes the system have the same life as the engine. The main function of the timing belt is to drive the valve train of the engine, so that the intake valve and exhaust valve of the engine can be opened or closed at the appropriate time, and the cylinders of the engine can be normally sucked and exhausted. The timing belt of some models is also responsible for driving the water pump, such as Jetta EFI, Santana 2000, Bora and Audi. For all engines, the timing belt must not jump or break. If the engine cannot work normally once it jumps, there will be unstable idle speed, poor acceleration or non-stop. If the timing belt is broken, the engine will shut down immediately, and the multi-valve engine will also cause the piston to bend the top valve, seriously damaging the engine. The timing belt is a rubber part. With the increase of engine working time, the timing belt and its accessories, such as timing belt tensioner, timing belt tensioner and water pump, will wear or age. Therefore, all engines equipped with timing belts will have strict requirements, and the timing belts and accessories will be replaced regularly within the specified period. The replacement cycle varies with the engine structure. General vehicles will be replaced when they travel to 60,000 ~ 654.38+10,000 kilometers. The specific replacement cycle is subject to the vehicle maintenance manual. The above is the difference between timing chain and timing belt. I wonder what the new Alto is?
