Recently introduced, Magno-Truck, has been developed after the success of Magno-Flo and the need to not only reduce fuel costs, but emissions as well.

Similar to our Magno-Flo fuel saving device, Magno-Truck is also designed to fit without cutting into the fuel lines and does not require any adjustment o your management system. The Magno-Truck Unit conditions the fuel to burn more efficiently, giving you the same power, using less fuel, with less emissions.

Magno-Truck has been used to conduct trials with an Ultra-sonic Flowmeter on a selection of engines including a Volvo Refuse Vehicle, an MAN 480hp and a 250KVA Generator.  The results of these trials can be viewed below.
 

 Results of Flowmeter Trials Conducted on a Refuse Vehicle
-Dennis fitted with a Volvo FM9 diesel Engine

The refuse vehicle for trialing had been fitted some months previously with my fuel saving
unit and so was bedded in. The fuel monitoring was conducted by using a Katronic 220
Ultra-sonic Flowmeter supplied and calibrated by Katronic. The flowmeter came with two
transducers; one to monitor the fuel feed flow to the engine and one for the return pipe.
The monitoring was conducted in litres/hour, prior to commencing trials the vehicles
engine was run for 10 mins to warm up. The trial was based on full revs with, and without, the fuel saving unit in place.
 

Results ltr/h

With Magno-flo unit fitted

Fuel feed flow 83 Return pipe 77 Consumption 6

Magno-flo Unit removed, engine left to idle for 10 mins

Fuel Feed flow 83 Return Pipe 76.4 Consumption 6.6

Test conducted has shown a 10% fuel reduction when the Magno-flo unit is fitted. This figure, going by The Bolton Institute reports, will increase when the engine is under load, hence we have reports on HGV's obtaining a 14% better fuel economy as well as increased torque.

This trial took place on Wed 27th January, 2010, at the premises of Swansea Council, and was overseen by Terry Avery, Fleet Manager
 

Results of Flowmeter Trials Conducted on an MAN 480hp Tractor Unit

Fuel trials were conducted on Saturday, 30th January, 2010. The vehicle used in the trial was an MAN sleeper cab tractor unit. The fuel monitoring was conducted using a Katronic 220 Ultra-sonic Flowmeter complete with two transducers for to monitor the flow and return pipes. The vehicle to be tested was firstly run to achieve operating temperature. The transducers were fitted to the flow and return pipes, close to the fuel tank, monitoring was at idle speed and at 2200 rpm. Figures were noted, the vehicles engine was then fitted with the Magno-flo unit clamped onto either side of the fuel feed pipe, close to the pump. The vehicle was then revved to 2200 rpm for 10 mins to give time for the Magno-flo unit to settle in, readings were taken again at idle speed and at 2200 rpm. When monitoring the figures the transducer fitted to the feed pipe was stable giving a consistent figure, whereby the transducer fitted to the return pipe varied by around 8ltrs/hr, in this instance we took the highest and lowest figure shown to obtain an average.

Monitoring was based on ltrs/hr.

Flow Pipe Return Pipe Consumption

Test 1 without Magno-flo units
Idle speed 79 75.64 3.36
2220rpm 105.43 98.00 7.43

Test 2 With Magno-flo Units
Idle Speed 79 76 3
2200rpm 111.29 104.6 6.69

The results show at idle speed a 12% fuel saving and at 2200 rpm an 11% saving. These figures, going by The Bolton Institute reports, will increase when the engine is under load, hence we have reports on HGV's obtaining a 14% better fuel economy as well as increased torque.

Having completed various trials with haulage companies, using various types of trailers etc, etc, there is not an on-board fuel monitoring system on the market capable of giving an accurate measurement of fuel consumption on a vehicle because they cannot take into consideration changes in the weather conditions, load type or weight carried, all of which carry a huge variable. I have reports of vehicles obtaining 6.5mpg on tipper work, same type of tractor unit on fridge work reporting 9mpg – a 40% variable.

 

Results of Flowmeter Trials Conducted on an Iveco Powered Generator

Fuel trials were conducted on Friday 22nd January, 2010, on a 250KVA, 6 cylinder, Iveco diesel generator. Engine is permanently running and is under constant load, although is never under full load. The fuel monitoring was conducted using a Katronic 220 Ultra-sonic Flowmeter complete with two transducers for to monitor the flow and return pipes. When monitoring the figures the transducer fitted to the feed pipe was stable giving a consistent figure, whereby the transducer fitted to the return pipe varied by around 8ltrs/hr, in this instance we took the highest and lowest figure shown to obtain an average.

Monitoring was based on ltrs/hr.

Flow Pipe Return Pipe Consumption

Test 1 without Magno-flo units
Part load 110 84 26
90-100KVA Load 114.6 81.5 33.1

Test 2 With Magno-flo Units
Part Load 110 87.12 22.88
90-100 KVA Load 111.29 81.99 29.29

After an initial fitting of the Magno-flo unit the results showed a 13% fuel saving. We would anticipate that this percentage saving would increase due to excess of carbon deposit that has built up in the engine which the Magno-flo unit will clear through time due to the better burn point that the unit produces. This engine is not under its load capacity as can be seen by the visible smoke when it has a 90KVA load added which is around 1/3 of its capacity.
