What causes the lack of acceleration in the Changan CS75?
2 Answers
Obstructed intake or exhaust, clogged fuel lines, inaccurate ignition timing, clutch slippage, or even a faulty brake caliper causing the brakes to drag, as well as underinflated tires, can all manifest as a lack of acceleration. Related introduction: 1. Overview: The Changan CS75 is positioned between the CS55 and CS95 as a compact SUV, equipped with the Blue-core series engine. 2. Powertrain: In terms of power, the Changan CS75 offers two engine options: a 2.0L naturally aspirated engine with a maximum power output of 158 horsepower, and a 1.8L turbocharged engine with a maximum power output of 177 horsepower and a peak torque of 230N·m. For transmission, it is paired with a 6-speed manual gearbox or Aisin's new-generation 6-speed automatic transmission.
I experienced sluggish acceleration when driving my Changan CS75, feeling delayed throttle response as if encountering resistance. Later inspection revealed severe carbon buildup in the throttle body requiring thorough cleaning. Multiple causes exist: a clogged air filter restricts airflow affecting combustion; a dirty fuel filter causes insufficient fuel delivery reducing power; aged spark plugs with inaccurate ignition are common culprits if overdue for replacement. Exhaust system blockages or catalytic converter failures also impair acceleration. Though less frequent, transmission issues like delayed automatic gear shifts manifest as power loss. Regular highway driving helps prevent carbon deposits, but professional maintenance is necessary for severe cases to ensure travel safety.
