Diesel PHEV: Chery KP31 is the ute Toyota should've built years ago

Chery has officially revealed the KP31 concept ute for Australia — and the headline is a 2.5L turbo-diesel PHEV with a claimed 47% thermal efficiency.That’s not just another me-too dual-cab. If Chery executes this properly, it could be a genuinely disruptive ute: diesel torque + towing credibility + hybrid assist for better urban efficiency.In this video I break down:why this is probably a diesel-led hybrid (not a Shark 6-style setup)the most likely powertrain layoutwhat the 47% thermal efficiency claim actually meansand whether KP31 is a real threat to Ranger and HiLuxIf you’re thinking about your next dual-cab, this is one to watch.#Chery #KP31 #Ute #PHEV #DieselHybrid #Ranger #Hilux #Shark6 #CannonAlpha #AutoExpert

How To Hot Blue Mild Steel With A Blowtorch And Oil

If you’ve ever wanted to give low-carbon steel a tougher, darker, more interesting finish in the home workshop, this video shows you how to hot-blue steel with a blowtorch and linseed oil.This is a simple, old-school workshop finish that can look fantastic when done properly. It’s not magic, and it’s not the same as a factory gun-bluing process — but for the right project it can give mild steel a dark, rich, characterful finish with minimal equipment.In this video I cover:how to hot-blue low-carbon steelusing a blowtorch to heat the steelusing linseed oil as part of the finishing processwhat the steel is doing as it heats and colourshow to get a more even resultwhat kind of finish you can realistically expectand the limitations of this method in the real worldThis is practical DIY workshop finishing — not showroom nonsense.So if you’re working with mild steel, making a project at home, restoring a part, experimenting with steel finishes, or just want a simple way to make fabricated steel look more deliberate and less raw, this report should help.Topics covered include:hot bluing steelbluing mild steelblowtorch bluinglinseed oil steel finishDIY steel bluinghow to blacken steelhow to colour steel with heatmild steel finishingworkshop metal finishinghome shed steel projectsAs always, this is about practical results, realistic expectations, and doing better work in a real shed.#bluing #steel #metalfinishing #mildsteel #blowtorch #linseedoil #diy #workshop #fabrication #welding #howto #homeworkshop #autoexpert #johncadogan

Blow Torch Science: Propane vs Butane vs MAP-Pro vs Oxy-Fuel Explained

If you want to understand how blow torches actually work, this video is a technical deep-dive into the combustion chemistry and physics of torch design — including the differences between butane, propane, Trade MAP / MAP-Pro, and the role of air vs oxygen as the oxidiser.This is not just a product comparison.It’s an explanation of what is actually going on in the flame:how different fuel gases burn, why flame temperature changes, what oxygen really does, how torch design affects performance, and why some setups are dramatically better for heating, brazing, soldering or cutting.In this video I cover:blow torch combustion chemistryhow propane burnshow butane burnshow MAP-Pro / Trade MAP burnsair-fuel vs oxy-fuel torch designflame temperature and heat transferhow oxidiser choice affects torch performancewhy oxygen changes everythinghow torch design affects efficiency and usable heatwhy hotter is not the whole storyIf you’ve ever searched for:propane vs butane torchMAP-Pro vs propaneoxy propane vs air propanehow blow torches worktorch flame temperaturecombustion chemistry of propanehow oxygen affects flame temperaturebest gas for a blow torchtorch design explainedbrazing torch science…this report should help.The aim here is to explain the underlying science clearly enough that you can make better decisions about torch selection, performance, safety and real-world use in the workshop.#blowtorch #propane #butane #mappro #mapgas #oxytorch #combustion #chemistry #physics #brazing #plumbing #welding #homeworkshop #tools #autoexpert

Which Blow Torch Is Right For You? Butane vs Propane vs MAP-Pro vs Oxy

Trying to choose the right blow torch for your shed?In this video, I compare butane, propane, Trade MAP / MAP-Pro, and the difference between using air or oxygen as the oxidiser — because the “best” torch depends entirely on what you’re actually trying to do.If you just want to heat something up, loosen a stubborn bolt, do some light plumbing, braze properly, or avoid buying an overhyped setup you don’t need, this report will help.I cover:butane vs propane vs MAP-Proair-fuel vs oxy-fuelwhich torch burns hotterwhich setups are actually useful in a home workshopwhat’s good valuewhat’s overkilland which torch is the right tool for different jobsThere’s a lot of confusion in this space, and plenty of marketing nonsense. Some torches are cheap but limited. Some are hotter but cost more to run. Some sound impressive, but make no practical sense in a normal home shed.This is a practical guide to help you choose the right torch once — based on what you actually do, not what the packaging claims.So if you’ve ever asked:Which blow torch is best?Is MAP-Pro better than propane?Is butane enough?Does oxygen make a big difference?Which torch should I buy for a home workshop?…this one’s for you.#blowtorch #propane #butane #mappro #mapgas #oxytorch #brazing #plumbing #diy #workshop #tools #homeworkshop #welding #autoexpert #johncadogan
