Malakas ba sa gas pag lagi nag start engine?

[wakpng1986]

Question guys.
1. Malakas ba konsumo sa gas everytime we start the engine?
2. Mas okay bang wag patayin ang makina kung mag idle ng 30 minutes?


hindi po ,,mas malakas ang kunsumo ng gas pg nka idle kayu..gas kc yan basta na andar makina nyo tloytuloy na konsumo nun,pg diesel po ata hindi mastipid pa pg naka idle

Guys thank u sa mga sasagot

hindi po,,. malakas tlaga sa gas pg nka idle lang.sa palagay ko po sa diesel un effective,mas ok pa naka idle kysa mag start ng engine.

Salamat sa inputs pero meron ba tayong technical o scientific o mechanical explanation na 'HINDI MALAKAS ANG FUEL CONSUMPTION PAG NAG START NG ENGINE?"

The engine upon start up gulps fuel, observe your tachometer upon start up it kicks as high as more than 2k rpm before it gradually descend to the idle speed

An engine idles at 700-800 rpm and peaks at 1k rpm when the aircon compressor couples to the engine

From there you can compute and deduce which consumes more fuel. The more revolution, the more fuel that gets burned

Assuming the tachometer needle goes up and down for 2sec in 2000rpm (66.667rev). With the gradual descent to idle speed pegged at 1sec for 1500rpm (25rev), another 1sec for 1000rpm (16.667rev), another 1sec for 800rpm (13.333rev). So after 5secs upon start up the engine rotated for a total of 121.667rev. For a minute it will be 855revolutions. For 2 minutes it will be 1655rev. For 3 minutes it will be 2455rev

The same engine that idled for 5sec at 800rpm will result to 66.667rev. For a minute it will be 800revolutions. For 2 minutes it will be 1600rev. For 3mins it will be 2400rev

The same engine that idled for 5sec with aircon compressor coupled for a span of 2s will revolve for 73.333. For a minute it will be 806.667revolutions. For 2minutes it will be 1606.667rev. For 3minutes it will be 2406.667rev

Based on these computations the engine revolution will always be higher with engine start up.

I hope that satisfies your curiosity

Punuin mo kasi fuel tank mo. Matakaw talaga sa gas pag kokonti laman ng fuel tank. Malakas talaga mga new model sa fuel pag naka idle kasi gumagana palagi EVAP.

The 30minutes idle scenario is practical only in the parking lot. In other words you dont stay idle for 30minutes in an intersection or on the road

And its always more frugal to shut your engine if you dont intend to move for a long period of time

Fuel drives a combustion engine and it doesnt matter if its gas or diesel. In the absence of fuel the engine stalls just like when a fuel tank gets dry.

Sa 01 E150 4.6 V8 30 gallon fuel tank return type fuel system. Basta puno yung fuel tank 1 hour idling di pa aabot ng 1liter/hr. Basta yan dala ko inaabot ako 2-3hrs idling. 3 yung fuel line from fuel tank supply, return at evap. Saka lang gumagana EVAP pag 85% na lang fuel level. Basta gumana na yung pesteng EVAP na yan parang may butas fuel tank sa lakas ng fuel consumption. Kaya nga madami noon ang naniniwala na matipid pag konti laman ng fuel tank kasi pag below 15% na lang fuel di na gumagana EVAP.

Pag 2012 CRV gamit ko di ako makapag idling kasi napakatakaw sa idle. Malakas pa lumamon ng fuel kesa sa F150 ko na 4.2 V6 OHV. FACT: Mas tipd sa Fuel consumption ang overhead cam kesa overhead valve engine. Mas matakaw pa sa 5.4 SOHC V8 ang 4.2 V6 na OHV. Ang advantage ng OHV over OHC are reliability. Masarap pati idrive OHV kasi malakas Torque.


Kalokohan yung computation ng fuel consumption. Hindi naman Air ang kailangan para masunog ang fuel kundi oxygen. Ilan % lang ba ang oxygen sa air? Based on scantool 1.3-1.5 liters / hr daw fuel consumption. Pero pag pinakargahan ko pahirapan pa masalinan ng 3 liters.

Scam yang pesteng EVAPORATIVE EMISSIONS na yan. Clean the air by burning more Fuel without producing power. Isn't it stupid? Sa halip na I condensed yung mga nagiging fuel vapor pinapasunog sa catalytic converter without producing power. Kaya nga ginawang electronic yung throttle body kahit marami na naaksidente dahil sa SUA para makapag purge ng fuel vapor sa idle. Pag manual kasi throttle body pag nag purge yung EVAP sa idle mag stall yung engine. Saka lang nakakapag purge yung EVAP noon kasabay ng EGR pag mataas RPM.

Kaya napakamahal ng fuel dahil sa pesteng media na reliable source of wrong information. Sa Venezuela gasoline only cost $0.06 USD per US gallon. Pang 10th place lang Venezuela sa world's largest oil producing country worldwide. Tingnan mo kung anong country yung nasa 3rd place today. Sila yung 1st place noong 2014. Pano ba naman hindi tataas yung price ng oil yung 3rd largest oil producing country nag impoport ng oil sa halip na nag eexport. Compare mo price ng diesel at gasolina sa US at sa pinas, Sa US self service pag pag pump ng fuel. Natawa nga sa akin yung cashier kasi tinanong ko kung pano mag pump ng fuel nung nag punta ako ng US. From what cave, mountain or stone aged country daw ako galing at hindi ako marunong mag pump ng fuel in english. Sabi ko, Sorry I'm came from 3rd world country. Gas station employs people who pumps fuel for me, check engine oil, coolant, tire pressure and cleans my windshiled at no extra cost.

FACT: AViation Fuel aka AVGAS is still leaded until today. May unleaded din Peteon Blaze 100 octane pero requires more maintenance at mas mataas risk ng engine failure. Madumi sunugin unleaded at mahina hatak. Yung 2 seater na Cessna 152 ang average fuel consumption ay 6 gallons per hour.

Wag mo alalahanin ang fuel consumption during start up, mas alalahanin mo ang starter mo.
