[crossed out] X3456 Hs{Lord Ernest Hives - Chair}1/LG8.9.24. OVER-HEATING. X766 X3456 [crossed out] Our tests have proved that we get less heat to the water with [redacted] a high compression compared with a low compression engine. Our customers on the Continent claim that the high compression engines heat less water. Attached here-with is our explanation for this. Hs.{Lord Ernest Hives - Chair} | ||
