👉 Cam fumes, often referred to as cam oil vapors or engine oil vapor, are a byproduct of internal combustion engines, particularly those using gasoline or diesel fuel. These vapors are primarily composed of hydrocarbons, which can include various alkanes, alkenes, and aromatics, along with smaller amounts of other compounds like alcohols, ketones, and sulfur-containing substances. The fumes are typically odorless but can have a distinct, pungent smell, often described as sweet or gasoline-like, especially when the engine is running at high temperatures. Prolonged exposure to cam fumes can be harmful, affecting the respiratory system and potentially causing irritation or long-term health issues. To mitigate these effects, it's advisable to ensure proper ventilation in the engine compartment and avoid direct inhalation of the vapors.
