Ford Probe Brochure Page 18 - Probe Power: DOHC 24-Valve V6 & I-4 Engines

This is page 18 of a Ford Probe sales brochure, titled "Probe Power." The page pairs marketing text with a large photograph of the Probe's engine bay, prominently showing the V6 engine with its "V6" and "DOHC 24-VALVE" valve cover badging and a Ford logo. The text explains the powertrain philosophy behind the Probe's engines: both the multi-port fuel-injected I-4 and V-6 use a free-breathing 4-valve-per-cylinder design with dual overhead camshafts. It describes how the powertrain engineer's goal is to inject a precisely metered fuel/air mixture into each cylinder quickly, burn it evenly and rapidly, and release exhaust efficiently to extract optimum power from every drop of fuel and deliver responsive power and torque across the performance range. The design uses four valves per cylinder (two intake, two exhaust) with belt-driven twin overhead camshafts, one for intake valves and one for exhaust valves. The brochure notes that four valves versus two deliver higher flow and velocity of fuel/air, promote greater rapid-burn combustion for higher power output, and that the smaller, lighter valves allow low-tension springs so the engine can reach higher rpm more quickly. No fuse data, part numbers, or specific model year appears on this page.
