What are the effects of a cracked engine intake hose?
2 Answers
Engine intake hose cracking can cause vehicle shaking and insufficient engine power. Below is a detailed introduction to the engine intake system: 1. Composition: The engine intake system is the passage for air to enter and exit the air filter. The intake pipe connects the air filter to the carburetor manifold, while the intake manifold is the pipe that connects the bottom of the carburetor at the upper end to the intake valves on the cylinder block at the lower end. 2. Function: The intake pipe includes the main intake pipe and branch intake pipes. In addition to power performance, the engine must also have good fuel economy and emission performance. In gasoline engines, the intake pipe must also consider issues such as fuel atomization, evaporation, distribution, and pressure wave utilization. In diesel engines, it is required that the airflow forms an intake vortex in the cylinder through the intake system to improve mixture formation and combustion.
Last time I took my old car for a countryside trip, I heard a strange hissing sound halfway and smelled oil. Later I found out it was a cracked intake hose. When this thing cracks, dirt gets sucked directly into the engine. Dust and debris accumulate there, causing severe engine vibration, loss of power, and a noticeable increase in fuel consumption. That repair cost me over 300 yuan. Otherwise, it might have damaged the cylinders, leading to a major repair costing thousands – that would've been a huge loss. I also learned to check for such issues by listening for unusual sounds and monitoring fuel consumption changes, which helps detect problems early. It's best to inspect the hose during routine maintenance rather than waiting for a breakdown. Hose aging is common, especially in older cars, and they're prone to cracking during significant weather changes, so timely replacement is crucial.
