Hi, i shall not make the pump and popoff injector , because it is difficult for me.

It is very very small fuel for each injections in the modelengine + how much it can give precise quantity fuel each injection in high rpm..
To example a truck engine at 4000 rpm use 3 cubicmillimetre (0,000183 cu/in) diesel for each injections.

I am thinking if it is possible at model dieselengine with pump, maybe engine will consume 1/4 of fuel tank while model dieselengine with carburator consuming 1/2 of fueltank.

One problem, where are the lubrication of engine if it has dieselpump and popoff injector, we can not use oil in out 4 stroke crankcase to lubricate moving parts.[]

Today i am ready (not complete) with my Magnum XL 52 fourstroke. Has converted the engine to dieselengine.
And i has mixed new 4 stroke dieselfuel, i has never runned engine with glow or methanol/oil/nitro. Only new engine, then i slaughted [>:] new unused engine and maked engine to be a dieselengine. [8D]

Engine has Lanova combustion camber with contrapiston, all works well, not much carbon cause rich fuel while break in.

Now i am breaking in the engine, it ran without problem in cold weather -1 celsius (can not fahrenheit temperature).

Dieselfuel formula: 32 % ether, 10% castoroil, 10% 20W50 full synthetic motorcycle 4 stroke motoroil, 48% diesel (not kerosene, because diesel has better lubrication perfomance). Also i has all 3 things to lubricate engine: Diesel (we use diesel to lubricate dieselpumps in our cars), castoroil, 20W50 full synthetic motorcycle 4 stroke motoroil.
