12v Bio Transfer Pump

Bought this pump from Ebay. 38mm o.d so it can fit into containers through the screw cap opening. Its brilliant, no more lifting heaving containers to fill the car.

SKODA OCTAVIA 1.9 PD (2010) Last of the Pump Duse!

Guys, bit of a disaster recently. My poor Passat's steering rack developed a hydraulic leak @ 205k miles :-(. Too costly to replace so I trading it in for a Skoda Octavia Esate 1.9 TDI. 

Like the title says, 2010 is the last year Skoda used Pump Duse injection for the VW designed BXE engine. Significantly biodiesely compatible, but that's not all - there's no DPF (diesel particulate filter) Whoop whoop.

Started on a 60% bio/diesel mix  and now on 100%. Cars done 70k.

Not long before I reach the 200k mark. Fixed the intercooler pipe a while back by drilling in self tapping screws (the VW clip is pretty much useless!)

Fitted winter tyres this year (not that I needed them since its been so mild...Typical) and I have a spare set of alloys I got off ebay for £150 with two decent Avon tyres.

The brake callipers are starting to show some corrosion and are difficult to home with the VW tool so they might need replacing with reconditioned ones sometime. Had the drivers side upper ball joints replaced and its feeling sturdier to drive.

Cam Rebuild - Lots of Wear at 187k

5/31/2013

3 Comments

 
Not bio related! PD engines are unique in the way they inject the fuel, using individual unit injectors being pressurised by the overhead camshaft. Fine tollerances and high pressure eventually lead to wear of the lifts and cam lobes.

Car was running rough, OK on idle but felt like three cylinders at 50-60mph. Now the cam has been completely rebuilt, just got to stop the turbo blowing off the intercooler pipe...

Vacuum Venturi Aspirator - Methoxide Injector

Vacuum Aspirator - Methoxide Injector
Strong Vacuum - Lifts Liquids above 1.5m


Making biodiesel can be potentially dangerous, methanol is toxic and sodium or potassium methoxide is both toxic and corrosive.

Eliminate your risk of exposure to methoxide by installing a vacuum aspirator into your biodiesel reactor. The flow of liquid alone creates a one way vacuum, sucking methoxide (or any liquid) safetly into the reactor.

Additional advantages include

1) Rapid feedstock drying by leaving the inlet open, airating the wet         vegetable oil

2) Your pump does not have to tolerate corrosive methoxide, extending its lifespan.

3) Fire risk is reduced, safer environment for the biodiesel operator.

4) Postive pressure created in the reactor, optimising methanol recovery via a condenser.

These vacuum aspirators are made from PVDF (Polyvinylidene Fluoride) which is resistant to hydrocarbons and corrosive chemical attack. PVDF is an advanced thermoplastic, used in specialist applications and tolerates a temperature exceeding 150c.

Fitted with 3/4" NPS screw threads, ideal for connecting to 22mm pipe work. You can either source a NPS to 3/4" BSP adapter or do what I did in the video and scew into 3/4"BSP with PTFE tape to create a seal.

Eductors

Eductors are a cost effective way of boosting your pumps power (flow output). The Eductor forms a jet, additional liquid is drawn through the nozzle via the Venturi effect. Flow rates can be boosted to 5 x with this inexpensive nozzle. Visit the shop for more info

Oxford Catalysts Donates a Centrifuge

2/4/2013

0 Comments

 
The nice people at Oxford Catalysts have donated a centrifuge designed to clean waste oil and biodiesel! I'm looking forward to installing it this summer, the ultimate in fuel purification.

Powered by a high gear pump, the centrifuge is powered by the pressurised fuel itself, spinning the main rotor head at high velocity. Particles that weigh almost nothing become much heavier, separating from the fuel.
