my daughter just began to read and write and is presenting a notable  aptitude to the mechanic, the hack-mechanic, I am glad to use this excuse to share quality time at home with her.

Listeroid Engines / engine knock review.
« on: January 10, 2008, 03:31:39 PM »
hi, After listen opinions about my engiene sound, I took tis footage with the microphone covered with a finger (to ear only the hammer noise, is confirmed, this engine is knocking too loud. Today or tomorrow I'll remove the cover to inspect the crankshaft bearings and rod bush and bearing. The results will be posted, for now apreciate the sound in the video.http://youtube.com/watch?v=zeBlxjL5dT8

Listeroid Engines / linkage arragement to improve the speed regulation.
« on: November 14, 2007, 02:39:26 PM »
this simple arragement of the spring, can bring a speed improvement like 62Hz (no load) to 59.8Hz full load), before the spring realigment, the speed dropped to 57Hz. The explanation is that with the original spring setup (made for a stationary engine, no necesarely for generation aplication) the spring bends during the travel, when bends the spring loose the proportionality L/K, when L: travel lenght and K: spring proportionality constant.

is working to me, the cost was 50 Cents and a little hobby time.

THIS IDEA WAS TAKEN FROM THE UTTERPOWER.COM PAGE.

Waste Motor Oil / inspection results after a long test using WMO.
« on: October 22, 2007, 10:49:00 PM »
Hi,

I PERFORMED A TEST USING WASTE MOTOR OIL, THINNED WITH 40% KEROSENE AND FILTERED TO 2 MICRONS. AFTER 500 RUNNING HOURS WE DISASSEMBLED THE ENGINE, THE RESULTS WAS:

1) PISTON TOP WITH A CROASE CARBON DEPOSIT, JUST THE NECESSARY TO TOUCH THE CYLINDER HEAD.
2) PISTON GROOVES CORBONIZED.
3) EXAUST VALVE VERY CARBONIZED.
4) SOME MINOR CYLINDER LINER SCRATCH.

TALKING ABOUT THE ENGINE PERFORMANCE AND FUEL EFICIENCY, WHEN USE DIESEL THE EFICIENCY (WITH A RESISTIVE LOAD OF 80%) IS 12.5 KW-H PER GALLON, WITH THE WASTE ENGINE OIL BLEND ITS DECREASE TO 9.5 KW-H/GAL.

I PERSONALLY, DO NOT RECOMEND THE USAGE OF WASTE ENDINE OIL AS FUEL, IS CHEAP, BUT THE INTERNAL ENGINE CONTAMINATION DO NOT PAY FOR THE COST/PROFIT RATIO.

Listeroid Engines / lovson 8/1 engines without oil pump.
« on: October 10, 2007, 03:16:04 AM »
hi people,

have anyone experience with the lovson engines 8/1, this engine comes without oil pump. I am testing the mine since more than 100 operating hours ago, recently I removed the inspection cap (the oil measuring stick side) and all looks to be ok, the crank case is clean and are not signals of wear.

my question is because many other models brands make emphasis in the (gun metal) oil pump, comments and experiences are appreciated. ???

Listeroid Engines / light bulbs flicker solution.
« on: September 18, 2007, 02:13:28 PM »
Hi,

recently with my new listeroid I had som light flicking problems, the radical solution was to replace the ST brushed generator with a brushless one by the brand YANAN made in china too, I took the generator from other plant that I own. The YANAN generator have an electronic voltage regulator with stability adjust, first I setted the stability with full loas until stop flikking, them, whet retired the load was necesary to do some fine adjust with no load (testing with an incandescent lamp), the flikking lights was resolved.

My suggestion is to choose an electronically regulated generator, prefferable a brushless one.

Listeroid Engines / 6KW GENSET: LOVSON 8/1
« on: September 12, 2007, 06:32:34 PM »
HI,

TO THE PUBLIC CONSIDERATION HERE IS MY 6KW (5 KW. CONTINUOUS), I USED A 8/1 LOVSON, RADIATOR FAN VENTILATED (NIPONDENSO), 6KW. BRUSHLESS GENERATOR, AND A CUSTOM MADE FRAME.

Hi,

I am new in this forum. I have a large experience working standard diesel engines with a diesel - LPG mixture (40% diesel - 60% propane). I can report about  25 to 35% in the fuel bill, producing the same energy (KW/H) compared with plain diesel fuel. It works in any direct injection engine, I have this system installed on two cummins 6CT, one cummins 6BT and one yanmar TF-140. My next proyect is to install a new prototype system on a LOVSON 8/1.
