Why is the acceleration slower after replacing the timing belt?

Slower acceleration after replacing the timing belt may be due to misalignment. Below is more relevant information: 1. Effects of timing misalignment: If the timing is not aligned correctly, minor issues may include advanced or delayed ignition. Delayed ignition can cause unstable idling, weak acceleration, engine vibration, and reduced power. Advanced ignition may result in a metallic knocking sound similar to "clank, clank" when suddenly pressing the accelerator during engine operation. In severe cases, it can prevent the engine from starting, cause the valves to hit the pistons, and even lead to piston damage, bent valve pushrods, or broken crankshafts. 2. Function of the timing belt: The timing belt is a crucial component of the engine's valve system. It connects to the crankshaft and ensures accurate intake and exhaust timing through a specific transmission ratio.

How to Clean Intake Manifold with Walnut Shell Blasting?

Walnut shell abrasive media will tumble and impact within the enclosed intake manifold, effectively removing carbon deposits from intake valves and manifold walls. Here's more relevant information: 1. Walnut Shell Media: The raw material is purely natural walnut shells, eliminating concerns about chemical corrosion or pollution. Processed through crushing, rigorous screening, and multiple refining procedures, walnut shell media boasts high hardness, pressure resistance, and wear resistance. Its porous surface provides excellent adsorption capacity while being non-corrosive, non-toxic, and minimally soluble in acids, alkalis, or water. 2. Vehicle Safety: As an organic natural polishing material derived from walnut shells (not chemical compounds), walnut shell media won't damage workpiece surfaces. Using it for carbon deposit removal is engine-safe and delivers noticeable results.

Vans and trucks must have enlarged rear license plate numbers, and the number of spring leaf plates cannot be increased or decreased. The number of seats in vans cannot be more or less than specified, and a fire extinguisher must be present. The cargo compartment of a box truck cannot be modified (no side doors, no roof openings, no tailgates can be added). The size of the tires cannot be altered, and the tread patterns of tires on the same axle must be consistent. Vehicles with unresolved traffic violations or vehicles sealed by the court cannot undergo annual inspection.
